Another day, another excuse.

Dina Lohan denies that daughter Lindsay had any booze at an MTV after-party Sunday.

So why did her SCRAM bracelet go off?

"Somebody spilled a drink on her leg, which must have set off the SCRAM bracelet," Dina, 47, tells the New York Post.

The Mean Girls star, 23, was ordered to wear the alcohol-monitoring device last month after failing to appear in court stemming from her two DUI convictions.

But Dina insists, "She has done absolutely nothing wrong and shouldn't have to wear the bracelet in the first place. She is doing absolutely fine."

As Lindsay awaits a new hearing July 6, her mother hints that the actress is considering joining the next season of Donald Trump's Celebrity Apprentice.

"Donald is a friend of the family, and producers of Celebrity Apprentice have approached Lindsay to appear in the next season," Dina says. "She's deciding if she wants to do it or not, but she currently has three films in production, so she's very busy." See photos of Lindsay showing off her SCRAM bracelet.

A show rep wouldn't comment, insisting that it's "too early to talk about casting" at this time.
