The two, who star in the 1970s rock biopic "The Runaways," say Lady Gaga's got the look.
"She's really hot," says Kristen. "She's got a look."
Dakota says the pink one is just, like, really cool.
"I am a fan of Lady Gaga because I think she's a really good singer and a really great entertainer and when you watch her perform, you know it's going to be a show. I think that's really cool."
But even though the two play killer female rock stars in "The Runaways," neither of them is ever going to be gracing a stage any time soon.
"I would never karaoke," says Kristen. "Every time I've even tried to do that, I've regretted it two lines in, and I end up talking [the lyrics]. It's making me embarrassed talking about it."
"I would never karaoke," says Dakota. "I am so scared. That is the scariest thing. Getting up in front of a room of strangers and singing songs — that is so scary to me."
You could have fooled me girls! In "Runaways," Kristen plays the real-life legends Joan Jett and Dakota plays Cherie Currie and they both belt out tunes.
"I was playing somebody else," says Dakota. "[Karaoke] is like you getting up and doing that."
