She may be outspoken and famously stubborn in order to get her way, but there's one thing Omarosa Manigault-Stallworth admits to not succeeding at: her marriage.
The former Apprentice star – who was the contestant that viewers and the other players loved to hate – tells PEOPLE that she split with her husband of five years, Aaron Stallworth, at the beginning of the year but has kept it quiet.
"I wasn't as supportive to him as I could have been," says Manigault-Stallworth, 31. "He's home on the ranch (in Texas) and I'm in L.A. working on several projects."
The couple have yet to decide if they will file for divorce, but she says they are still best friends.
In the interim, she's filming Surreal Life 5 on VH1 and "just being Omarosa."
