Someone's in the dog house!

Teen Mom star Jenelle Evans' boyfriend Nathan Griffith bashed her pre-surgery body on Twitter Saturday night.

It all started when one Twitter user sent him a tweet about leaked topless photos of Jenelle before she got breast implants, that were exclusively published by Breaking Celebrity News.

Instead of defending his girlfriend, Nathan's first comment was, "Well, I'm lucky she doesn't look like that anymore sic."

"Plus, those pictures should of never got out," he added.

Jenelle's smaller cup size isn't the only part of her he's glad to leave in the past. Nathan insists she's sober now.

"People change and I wouldn't be with her if she didn't," he told another Twitter fan.

But is he with her for her money? Nathan is currently embroiled in legal and financial trouble, as Breaking Celebrity News exclusively reported earlier this week.
