Lindsay Lohan arrives for “Late Show.’ (Rob Kim/GETTY IMAGES)

Lindsay Lohan made headlines last fall when she stood up Barbara Walters for an interview, ditching her for Jay Leno at the last minute. Then, last week, Lohan continued her workaround of Walters, agreeing to sit down for an interview with David Letterman on CBS’s “Late Show.”

Though nothing is ever set in stone with Lohan, the actress indeed kept her promise to chat with Dave, making an appearance to promote her guest spot on Charlie Sheen’s FX comedy, “Anger Management.”

“Aren’t you supposed to me in rehab now?” Letterman asked right away in a 90-second clip CBS sent out early Tuesday evening, proving that Lohan showed up.

“Do you not watch anything that goes on?” Lohan shot back

They established that she will be in rehab starting on May 2, for three months.

“How many times have yiou been in rehab?” Letterman continued.

“Several,” Lohan replied.

Cheerfully ignoring the pointed one-word answer, Letterman grilled Lohan on what she’s going to be “rehabbing.”

“We didn’t discuss this in the pre-interview,” Lohan sniped.

But things seemingly went swimmingly from there: “Had a wonderful time at the @Late_Show. It was great fun! #iHeartDave,” Lohan tweeted after the taping.
