According to sources close to Usher and Tameka Fosters camps, the sex tape thats being peddled to the highest bidder purportedly shows Ushers ex-wife Tameka Foster pleasuring him with a strap on device. If youre not sure what that is, Google it.

TMZ was approached several days ago by someone claiming to have the sex tape. The person sent us a short video and two photos. Well keep this PG-13 and just say the people in the video are both givers.
The video and photos are clear its Usher and Tameka.
Sources close to Usher without specifically admitting the existence of a sex tape tell us they believe this video could have been among the things Usher had stolen out of his car back in December 2009. Usher reported more than $1,000,000 worth of jewelry and electronics taken including two laptop computers.
A rep for Usher had no comment.
UPDATE: Foster released a statement to TheYBF.com saying, Would I sanction a sextape being out? Absolutely not. I am a mother and entrepreneur. Sex tapes or pornography would not be my lane. I have no desire to be seen in that way.
