Olivia Wilde‘s kids are a little confused about their parentage — and for a hilarious reason.

One relevant topic of discussion? The huge framed artEllen DeGeneresgave the couple as a gag gift six years ago: a photo of DeGeneres in a yellow bathing suit, which used to hang above their bed and has since led their kids to a head-scratching conclusion.

“Now it has another very special place: outsidethe children’s bedrooms, soit’s the first thing that they see when they wake up,” said Wilde, 34.

“Do they say, ‘Who is that lady?’ ” asks DeGeneres, 60.

“Yeah, they say, ‘Oh, that’s our real mother,’ ” the actress jokes. “And I say, ‘Yes.’ ”

Wilde’s kids “wish they had the same room, which is very sweet” but for now sleep in separate bedrooms — and Daisy is currently trying to age herself up.

“She also lies about being 3, which is a really funny thing. You ask her, ‘How old are you?’ and she’s like, ‘I’m 3,’ ” says the mother of two. “I think she so badly wantsto catch up with her brotherthat she’s already lying about her age.”

Otis is currently hugely into music, like “theBeastie Boys, which we approve of wholeheartedly,” says his mom, alsorecalling the Beyoncé-themedsecond birthday party for her son.

“He also is into, weirdly … I don’t know how he discovered it, but Ibiza-style, techno, spring-break dance-party pop,” Wilde continues, joking, “We think he might be going out at night and hittin’ the ‘clurb.’ ”

“This is why you shouldn’tsend them to school— they come back with bad taste in music,” she kids. “We had done so well.”
