Controversial Couples Watch: Usher and Tameka Foster, Isaiah Washington and Wife

Not every Hollywood couple is as beloved as Francois-Henri Pinault and Salma Hayek.

Some pairings generate a great deal of controversy among celebrity gossip followers. Perhaps none more so than Usher and Tameka Foster.

Recently, the engaged twosome were shopping for sunglasses at the Solstice Sunglass Boutique in Beachwood, Ohio. The sexy singer bought five new pairs of aviator shades, all of which he had the chance to model at the recent 30th birthday party for good friend Kanye West.

Usher and Tameka were just two of the numerous guests in attendance, as West and fiancee Alexis Phifer actually performed together.

Also appearing as a united front in public last week? Isaiah Washington and his wife, Jenisa.

Days before the actor was dropped from Grey's Anatomy, People magazine reports that he and his lady dined at Santa Monica's One Pico restaurant at the Shutters on the Beach hotel, enjoying an ocean view at their table as they talked passionately over red wine and Pellegrino.

Maybe they were even talking about another celebrity couple that's hated on by the public.

After all, if Isaiah can go off on T.R. Knight, it's easy to see him bashing the heck out of Spencer Pratt and Heidi Montag, isn't it?

Let's just hope he left Ellen Pompeo and Chris Ivery alone. Those two have enough to deal with as they battle her anorexia rumors.
