Forever is shorter than they thought. Two weeks after wishing her husband Wiz Khalifa happy birthday with a sweet photo and promise to “love u forever” on Instagram, model Amber Rose filed for divorce in Los Angeles.

TMZ reported Wednesday that Rose filed documents to divorce her rapper husband of one year, listing their date of separation as Monday. Rose asked for full custody of their 19-month-old son Sebastian, though she specified Khalifa could have visitation. She also acknowledged they signed a valid prenup, and the documents seem to indicate it includes spousal support.

As the afternoon wore on, more information as to the reason for the already bitter split seemed to be leaking out. TMZ lists sources who said Rose was frustrated by Khalifa’s refusal to let her join him on tour. She is also allegedly accusing him of cheating. For his part, Wiz Khalifa is privately convinced Rose was being unfaithful, particularly with Nick Cannon, estranged husband of Mariah Carey, who has recently been working with the model to get her a TV deal. Cannon’s friends have denied the allegations.

Other than comments to reporters, neither Amber Rose nor Wiz Khalifa have formally commented on the split.
