Kim Richards, Kyle Richards

Why on earth is Kyle Richards returning to The Real Housewives of Beverly Hills for a second season?

You'd think she would have bailed after that that fiasco with her sister Kim.

It's not like Kyle doesn't have other things to do with her time. She's actually returned to acting…

She costars opposite Charisma Carpenter in Deadly Sibling Rivalry, a Lifetime movie premiering next month.

"Don't think too much into the title," Richards told us at the Lia Sophia jewelry event at the Sunset Marquis in West Hollywood. Ha!

The flick centers on a set of warring twins (Carpenter plays both) in which one is trying to take the identity of the other. Richards, who made her big-screen debut in 1978 horror classic Halloween, plays the evil sis' best friend.

Richards said she's also set to release a book and a handbag line come January.

RHOBH's sophomore season premieres on Sept. 5.

"The reunion was absolutely torture," Richards said of the first go-round. "It's absolutely torture because you see things that the girls are saying that you never knew they said about you, and all of a sudden you're like, ‘Wait a minute! I thought that we were friends? I thought we were OK?' "

So, why did she agree to come back?
