Lindsay Lohan isn’t going to let a little thing like work get in the way of a good time. The actress, 26, skipped the “Scary Movie 5” afterparty Thursday and instead drove with friends to Indio, Calif., for the Coachella music festival, which started Friday, E! reported.

Although Lohan has reportedly been “telling her close friends that she plans on keeping things clean and sober in preparation for her admittance into a rehab facility on May 2” — a source told E! that LiLo plans on “having a healthy fun time at Coachella” — she stopped for a “meeting at a nearby hotel” before hitting the road for the music festival. A late-night hotel “meeting” looks suspicious for someone who’s preparing to spend 90 days in court-ordered rehab.

But Lohan didn’t just leave the “Scary Movie 5” festivities early — she also showed up late. She was 30 minutes late to the premiere red carpet earlier Thursday — and like all the other problems in her life, it wasn’t her fault. LiLo blamed the delay on her stylist, who allegedly accidentally left the original dress she planned to wear to the premiere in New York City.

“The Dolce dress she wore arrived at around 6:50 p.m. and she put it on a little after 7:00 and bounded out the door. Traffic was jammed and she arrived at the red carpet at 7:42 p.m. The dress was 100 percent why she was late. At the end of the day she was very happy with the dress choice,” a “source close to LiLo” told E!, adding, “She had a really great time at the premiere last night. She received a lot of fan gifts and went through the letters last night.

Apparently Lohan and her stylist couldn’t find a dress earlier in the day so she wouldn’t be late to the premiere. But despite her tardiness, costar Charlie Sheen — who earlier this week during an appearance on “The Tonight Show” talked about LiLo holding up filming of “Scary Movie 5” and stealing some jewelry from the set — didn’t hold it against her on the red carpet.

“There is absolutely no hard feelings with Charlie at all,” E!’s source said.

Was Lohan really late to the “Scary Movie 5” premiere because of a wardrobe snafu? Will she be able to “keep things clean and sober” and “have a healthy fun time” at the Coachella music festival? Have she and Sheen buried the hatchet? Share your thoughts in the comments section.
