Kat Dennings of the hit comedy series "2 Broke Girls" is in awe of Kim Kardashian's butt, calling it "amazing".

The 28-year old voluptuous actress admitted on "The Ellen DeGeneres Show" that she was on edge about meeting Kardashian who was set to film a cameo on her show's 80^th episode. Upon meeting the "Keeping Up with the Kardashians" star, Dennings shared that she was awestruck by her much talked-about curves but was too shy to tell her about it.

''I didn't know what to expect because she's so famous. I was very nervous because I've seen so many episodes [of 'Keeping Up with the Kardashians'], and she was very sweet. She was very nice. And her a** is amazing! I am feminism, girl power, but I was just so in love with her a**. I just spit talking about it - that's how passionate I feel!'' Dennings admitted.

Dennings then continued to gush about her girl-crush on Kardashian, referring to her as "gorgeous" and amazing.

Of course, she kept on going back to Kardashian's derriere and even referred to an old episode of "Keeping Up with the Kardashians" when Kanye West, who was not in a relationship yet with the 34-year old star at that time, had mentioned that he has never seen an ass like Kardashian's before. Dennings confessed that she also had the exact reaction West had when she met her.

Aside from Kardashian's behind, Dennings is also raving about her new love, 33-year old singer Josh Groban who she feels is an absolute "wonderful person".

Her "2 Broke Girls" co-star Beth Behrs introduced Dennings to Groban whom Behrs has been friends for for years.

Dennings shared that Behrs always talked about how great Groban was and, eventually set them up because "she thought we were both, you know, nerds. So there, she was right.''
