This divorce between Usher and his soon-to-be ex-wife Tameka Foster just seems to get messier and messier. A new report from The National Enquier (insert obligatory side-eye here) says that Usher wants a paternity test done on his 6-month-old son Naviyd. Why? Because around the time the baby was conceived, Usher and Tameka were have very little to no sex.

“The first thing Usher said was, ‘How did this happen?’ – because he was gone a lot, and their sex life was very, very limited,” a friend of Usher said. “People have been telling him that around the time the little boy was conceived, Tameka got together with another man.”

Meanwhile, Tameka says Naviyd is Usher’s and she wasn’t the one being unfaithful at the time. She puts all the blame on Usher.

“She says that although they weren’t spending much time together, they did get together for one night of passion. And that’s when she got pregnant,” Usher’s friend said.

She was also reportedly surprised when she heard of her soon-to-be ex-husband filing for divorce, holding on to claims that they were intimate within the week of him making moves to end their nearly 2-year marriage. According to court documents, she’s disputing claims that they have been separated since July 2008 saying that she had every reason to believe her marriage was intact” and that two were “intimately together as husband and wife as recently as June 6.”
