Bristol Palin and Levi Johnston’s second engagement may have been even shorter than the first! Things seemed to be going well for the lovebirds who were undercover…until those pesky things like ex-girlfriends come out.

More pictures of Bristol after the jump…

Bristol reportedly called it quits when word leaked not about one ex potentially getting pregnant, but when another one said she might have hooked up with Levi. WTH?

Lanesia Garcia tells US magazine that she and Levi dated for 2 1/2 years but haven’t seen each other for several years. She says she knows who the father of her baby is, and it is definitely not Johnston.

“Levi is not the father of my baby,” she said.

That may not be enough for Bristol to go ahead with her wedding, however. A Facebook picture of Levi with another ex-girlfriend Briana Plum may have been the straw that broke the camel’s back for Bristol, E! News is reporting. “Bristol just said, ‘Let’s hold off on the engagement’,” a source told E!

So I wonder if Bristol and Levi get to keep all of that money from their exclusive cover shot announcing their engagement. It lasted what, two weeks? Do you think they should give the money back?
