2 Broke Girl star Beth Behrs should pack up the cupcake business and try her hand at setting people up. After all the actress had success with her first celebrity pairing, after she introduced new Hollywood couple Kat Dennings and Josh Groban.

Dennings appeared on Ellen to promote the new season of her CBS sitcom and the host asked about her current boyfriend.

"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," Kat reveals to the talk show host. "They've been friends for years. And she thought we were both, you know, nerds. So there, she was right."

During the interview, Denning's also revealed that Groban is a "wonderful person."

The couple began causing speculation about their budding romance when they hit the red carpet together and were photographed getting pretty close with each other. In one photo Kat is even spotted smelling Groban.

"They were so cute together," an insider told E! News. "They were adorable on the carpet. She was whispering in his ear a lot and they seemed really happy."

Also during the Ellen interview, Denning's talks about her time on set of 2 Broke Girls and working with guest star Kim Kardashian.

"I didn't know what to expect because she's so famous," the 28-year-old actress explains. "She was very nice. And her ass is amazing! I am feminism, girl power, but I was just so in love with her ass."

The news season of 2 Broke Girls will premiere on Monday, October 27 on CBS.
