If acting doesn't work out, Beth Behrs could be a professional matchmaker!

When Kat Dennings stopped by The Ellen DeGeneres Show Tuesday, she revealed that it was her 2 Broke Girls co-star who had introduced her to boyfriend Josh Groban. "He's very witty on the Twitter and I saw his little tweets...and sometimes we would [tweet back and forth]. But, yeah she's always talked about how great he is," she explained. "They've been friends for years. And she thought we were both, you know, nerds. So there, she was right." Dennings also called the 33-year-old singer a "wonderful person."

During the episode, Dennings also talked about another celebrity crush: Kim Kardashian!

The star of E!'s Keeping Up With the Kardashians appears in 2 Broke Girls' 80th episode. "I didn't know what to expect because she's so famous," Dennings, 28, recalled. "I was very nervous because I've seen so many episodes, and she was very sweet. She was very nice. And her ass is amazing! I am feminism, girl power, but I was just so in love with her ass. I just spit talking about it—that's how passionate I feel!"

Dennings was too shy to tell Kardashian that she was a big fan. "We would say a nice thing or two, talk about friends we know or people we have in common, and then she would turn around and Beth and I would [mouth], 'Oh, my God!' It's beautiful. She's gorgeous. It's just amazing. I've never seen an ass like that in my life," the actress admitted. "There's an episode of Keeping Up With the Kardashians—an oldie, a vintage one, before she and [Kanye West] got married—and she was doing her music video and Kanye was there and he was like, 'I have never seen an ass like that.' And that's what I was thinking!"

"And yet he got to her first," Ellen DeGeneres said. "You just missed out on that one."

"Such is my luck!" Dennings said.

Later on, Dennings played a round of "60 Seconds of Else" to raise money for breast cancer awareness. If she answered 10 questions correctly, nothing would happen to her. If she failed to do so, however, a mystery bucket would dump something on her. To Dennings' delight, the questions were related to cats.
