Casey Wilson is totes ready to let bygone be bygone!

The Happy Endings star (who plays unlucky-in-love, abbreviation-lover Penny on the show), 31, was infamously fired from Saturday Night Live in mid-2009 after less than two full seasons on the show. (Rumors swirled that the actress and comic was shown the door because she failed to lose weight at the request of show producers; SNL reps slammed the report.)

But with Happy Endings wrapping up its second smash season on ABC, Wilson told Us Weekly in a video interview she doesn't hold much bitterness -- and her latest success is "sweeter" having gone through that trauma. Still, "I don't love to fail," she admits.

In fact, she's got an ultimate bucket list goal: To go back to SNL as host!

In our exclusive sit-down with Wilson, she also dishes on Penny's potential romance with her pal Dave ("she will systematically destroy whatever she's in"), the "hilar abbrevs" her character dishes out on the show, details on her real-life boyfriend, and more!
