Lindsay Lohan and girlfriend Samantha Ronson canceled a joint Valentine's Day appearance in South Florida because they are too sick to travel.

The duo was scheduled to host and have deejay Sam spin at Passions, a Florida hotspot. "We really feel bad, and I work sick when I can, but unfortunately I couldn't drive to Miami, so I'm stuck in New York City with doctor's orders not to fly," Ronson revealed to People magazine. "Any reports otherwise are false and unfair."

"Lindsay and Samantha stayed out late last night in New York City, and are not feeling well," Amanda Senoff, Director of Marketing for Passions, told the magazine. "A doctor said Sam was too sick with the flu to travel and Lindsay is also feeling sick. So they rescheduled for March 7."
