Appearing on Watch What Happens Live Thursday, Lindsay Lohan denied partying at Coachella, slammed Rosie O’Donnell and suggested her mother Dina should join the cast of the Real Housewives of New York City.

The Mean Girls star didn’t flinch as they faced questions from Andy Cohen as she about her recent alleged partying. Lohan, whose OWN reality show, Lindsay, has chronicled her tardy and unprofessional ways after she got out of rehab last year, told Cohen the recent speculation about her at Coachella was dead wrong. As Breaking Celebrity News has reported, sources said Lohan had relapsed, as she was seen downing a vodka soda.

But when Cohen asked if she had been “partying” at the music festival, Lohan said, “No, I was not.”

She said of the famed desert rock music fest in California: “To be honest, this Coachella was the best time I’ve ever had going to Coachella. I’d gone there years when it was a different story. But this was the nicest trip I’ve ever had with my family.

“I was just with my family the whole time and then I went off on a Sunday by myself and watched Arcade Fire and Beck and it was really nice to be able to do that. I put a hat on and a scarf under that.”
