So Fast? Model Amber Rose Files For Divorce From Rapper Husband WizKhalifa After Just 1year!

As frequent as we hear about lovey dovey Hollywood couples who suddenly want to part ways, one can still never get used to the initial shock of hearing a couple, that seemed so happy together are getting divorced.
This evening TMZ broke the story that 'Black and Yellow' rapper Wiz Khalifa and model Amber Rose are getting divorced.
I am still very shocked about this.
Amber Rose reportedly filed for divorce from her baby daddy of 1-year today.
Interestingly, Yesterday, Wendy Williams said on her show that the 30 year old and Mariah Carey's estranged husband, Nick Cannon, have been getting 'very close' in recent months.
However Wendy watered down the story by adding that Amber featured in Nick's new movie and he is also managing Amber's career.
In the divorce papers, it is learnt that Amber is gunning for full custody of their kid but willing to give Wiz visitation. She also cites irreconcilable differences as grounds for the divorce.
Amber also  acknowledges there's a prenup and she's not challenging it. The divorce documents 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.
Sources connected with the couple also say the split is bitter.
What really is wrong with these Hollywood couples? Its not even been up to 2 months since they released their wedding photos. Pity the couldn't make it work.
