No boundaries for Hayden Panettiere's fans!

 During her Tuesday appearance on The Ellen DeGeneres Show, the Scream 4 star opened up about the very personal question curious folks ask most--regarding her much taller Ukranian heavyweight boxer boyfriend Wladimir Klitschko.

"He is quite a bit bigger than me," the 5'1" starlet, 21, said of her 6'6" beau, 35.

"I get the prudest people coming up to me and they're like, 'Does it work?' Yeah, it works. We find a way," the Heroes alum said.

DeGeneres, 53, couldn't believe fans would ask Panettiere about her sex life. "I know what you're talking about, but I'm in shock!"

"Where there is a will, there is a way!" Panettiere quipped about sex with Klitschko. She began dating Klitschko after her February 2009 breakup with her 33-year-old Heroes co-star Milo Ventimiglia.

"[The people who ask me how sex works with my boyfriend] are very conservative people most of the time but that just have to know," she explained. "Like, 'I have to know, I just have to ask you this question. I'm really sorry but…'"

DeGeneres said such personal questions were "crazy and rude," but Panettiere defended the TMI-queries: "I don't mind it."
