Bristol Palin on Breakup with Levi Johnston: ‘I’m Not Disappointed’

Bristol Palin said she's over Levi Johnston and dished about her "Dancing with the Stars" rehearsals on Friday's "Tonight Show."

Asked by Jay Leno how she feels about the breakup with her baby's papa, Bristol said, "I'm not disappointed. I'm not heartbroken."

"I tried to make it work for my son. It didn't work, and I realized that we're not meant to be, and I'm just focused on being a good mom," said Bristol, whose son with Levi -- Tripp -- was backstage.
