R&B singer Tyrese better get to singing and booking some gigs because American Express went full “Bitch Better Have My Money” and is suing the singer for $61,071.35.

Tyrese’s unpaid credit card balance isn’t the only financial woe he’s experienced this year, according to TMZ. The singer, a man who really thought it was smart to get on the Rock’s bad side, is allegedly in over his head when it comes to his monthly expenses.

In documents filed during his custody dispute with ex-wife Norma Gibson, Tyrese said that he brings in an income of $105,686 but had monthly expenses totaling $107,576. I don’t do math, but something tells me that Amex may never see that balance paid off.

You’d think that someone who didn’t have his financials together basically wouldn’t talk himself out of a job on Fast and Furious 100,000.
