They're the rocker boyfriends of fashion idols Paris Hilton and Nicole Richie, and now "Good Charlotte's" Madden brothers, Benji and Joel, are busy designing the goods! "Extra" goes inside Madden fashions, and correspondent Alison Waite got the first look at the brothers' hot new line.

Nicole and Paris joined their men at the opening of the Madden's flagship store, DCMA Collective, off of L.A.'s trendy Melrose Avenue. Benji talked about fashionista Paris' input, saying, "She's very supportive and she also likes it... that makes me feel good... you want the people you care about to be into what you're doing."

Benji is also feeling good about his role as "Uncle" to Nicole and Joel's baby, Harlow. "I have changed diapers," says Benji. "Need a babysitter? I will cancel everything. I love it."

Paris Hilton is shocking fans with her newest confession -- the party girl player is serious about Good Charlotte boyfriend Benji Madden... seriously in love!

Hilton recently divulged her happiness in a post on her MySpace Celebrity blog, where she wrote, "I've never felt so happy and in love... he's such an amazing guy and life has never been better." While her BFF Nicole Richie tends to new daughter Harlow Winter -- whose father is Madden's twin, Good Charlotte frontman Joel -- Paris has been rocking out on the band's tour, exclaiming, "It's been so much fun going to their shows... I now know every song by heart."

Could the "That's hot!" heiress be next in line for a Madden tot? Paris may think so, after confessing to Fox News last year that seeing Richie pregnant made her "feel ready to have a baby." This will undoubtedly lead to a new series called "Sisters-in-Law."

Reformed bad girl Nicole Richie has another new addition on the way - but this one is just for her wardrobe!

Harlow's mom is designing a new line of jewelry, according to People magazine, which she describes as "costume jewelry," adding, "I like to play with jewelry and mix and match." Who better than the stylish socialite to design a line of jewels? Her first book, "The Truth about Diamonds," was a bestseller.

The busy Miss Richie will also be releasing a clothing line for infants and children sometime in 2008. Does this mean oversized sunglasses and hippie scarves for kids of all ages?!

Through her representative, Nicole Richie has come to “Extra” to set the record straight in regard to a story claiming she has been smoking cigarettes while pregnant with her first child.

Richie’s rep tells “Extra” that the report is “irresponsible and untrue.”

The rep goes on to explain that Richie is traveling abroad with Joel Madden and is nowhere near New York, the city in which she was allegedly seen smoking.

“Extra” spotted the jail-bound starlet running some last-minute errands with boyfriend and rumored fiancé Joel Madden before turning herself in.

The pregnant star dropped her dogs off at the vet and picked up coffee from McDonald’s.

But it turns out Nicole never spent one second behind bars!

Nicole Richie has entered jail and left – in just over an hour!

According to the L.A. Sheriff’s Department website, Nicole entered jail around 3:15 p.m. today and left just after 4:30 p.m.

Documents show she was sentenced to five days for her DUI, but she snuck in and out, completely unseen.

The pregnant starlet, according to her booking information, now weighs 105 pounds.

Nicole Richie is finally giving the world a glimpse into her controversial life, admitting that it’s time for her to grow up and take care of her life – and her child’s.

Nicole originally claimed she was innocent after being arrested and charged with DUI for driving on the wrong side of the freeway, but a heartbreaking experience changed her mind.

“They started flashing pictures of little children that had been killed by people driving under the influence, and at that moment, I literally felt like the worst person in the world for even trying to get out of that situation,” a somber Nicole explained to Diane Sawyer.

Nicole Richie has confirmed her pregnancy, but we caught her talking babies back in April 2006!

While promoting season four of the now-cancelled 'The Simple Life,' Nicole divulged that she "cannot wait" to have kids. Three girls and twin boys to be exact!

Nicole told us that twins don't run in her family but it seems she's found a solution! Her baby's father Joel Madden is the identical twin to his brother Benji, both of who are in the rock band Good Charlotte.

Nicole Richie has finally admitted she’s pregnant, after months of speculation.

Now the jail-bound starlet is breaking her silence about her drug use, admitting why she took Vicodin the night she was arrested!

Lionel Richie is shrugging off reports that his daughter Nicole is pregnant, and he’s excusing her hard-partying ways as just part of growing up in the spotlight.

“She keeps apologizing to me,” he told People at the Essence Music Festival in New Orleans. “I told her, 'You're doing exactly what you're supposed to be doing to your father at this age.'"

Nicole, 25, is reportedly pregnant with rocker Joel Madden’s baby. She is also due in court later this summer to face DUI charges – her second offense. If she’s convicted, she could face jail time.

It’s the question everyone is asking: where is the guidance in these young girls’ lives?

Britney, Lindsay, Paris, Nicole – they’re the biggest stars of the party scene, and they’ve all been hit with a big dose of reality.

Britney and Lindsay are in rehab, Nicole faces a DUI charge, and Paris is in jail.

So where are the moms of Hollywood’s hellraisers?

“Simple Life” star and Hollywood socialite Nicole Richie has been charged with misdemeanor driving under the influence, TMZ.com reports.

On Friday, the DA charged Lionel’s little girl with being under the influence of "an alcoholic beverage and a drug."

Richie was arrested on December 11, 2006, on suspicion of driving under the influence when she was pulled over for driving the wrong way on the L.A.’s 134 Freeway in the wee morning hours.

At the time of her arrest, Richie admitted she had taken Vicodin and smoked pot, but never mentioned consuming any alcohol.

Nicole will be arraigned in Los Angeles County Superior Court in Glendale, Calif. on February 21.
