United state famous rapper Wizkhalifa after one year of marital bliss, Amber Rose his wife  just filed for divorce from rapper Wiz Khalifa. Wasn't it recently she shared wedding photos and gushed about him? 

her is the report from TMZ below..

.

Amber Rose has filed for divorce from husband-of-1-year old marriage  Wiz Khalifa ... and she's gunning for full custody of their kid.

In the divorce document  obtained by TMZ -- Amber says they split on Monday and cites irreconcilable differences.

She is asking for full legal and physical custody of their 1-year-old son Sebastian. She's willing to give Wiz visitation.

And this is interesting. Amber acknowledges there's a prenup, which you would think would work in Wiz' favor, but she says it's valid ... presumably, she's not challenging it. The docs say the prenup provides spousal support.

As for why they split, there's been a buzz over the last few days of infidelity, but there's no mention of it in the papers.

We got video of Amber with some guy Tuesday in Bev Hills. Our photog asks her if Wiz is keeping a close eye on Nick Cannon -- there are rumors they've hooked up, but she's mum.

Sources connected with the couple say the split is bitter.
