Usher sex tape leaks to media?

A sex tape that allegedly features 'OMG' singer Usher has been leaked to the media, it has been reported.

TMZ has obtained footage and two still photographs that supposedly feature Usher and his ex-wife Tameka Foster.

Sources close to the singer would not confirm that a sex tape featuring the star indeed exists but indicated that the erotic footage might have been among the items stolen from Usher's car nearly two years ago.

Among the items taken in the alleged theft were thousands of dollars worth of jewellery and two laptop computers.

Usher's rep has declined to comment on matter, while Foster's spokesperson could not be reached to provide a statement.

Usher and Foster were married in August 2007 in a private ceremony, but they ended their relationship just two years later. They are parents to 3-year-old Usher Raymond V and 2-year-old Naviyd.
