Couple Watch: Nick & Vanessa Strong; Silverman and Kimmel Too?

Something funny is going on with Sarah Silverman and Jimmy Kimmel—the two comedians are spending an awful lot of time together for having broken up months ago.

The pair officially announced their split in July of this year.  Reps for both refused to elaborate on potential causes the rift. Perhaps because there wasn’t one?

Sunday night, the 41-year-old talk-show host and his 37-year-old dirty talker made yet another post-breakup outing together.  The funny exes were spotted just last week at GQ’s Men of the Year party “hand in hand” by a Celebuzz source.  Sunday, they were at Target and Christina Aguilera’s Post-American Music Awards bash in Downtown L.A.

Romantic voyeurs will just have to wait to see a if reunion materializes between the chuckle heads.

In the meantime, be satisfied with a more-on-than-ever sighting of Nick Lachey, 35, and his lady Vanessa Minnillo, 28.

The former VJ, actress and upcoming reality host hit the red carpet in a sleep-soft mini with Lachey.  Nick wound up handing the Favorite Female Country Artist award to 18-year-old Taylor Swift.

Afterward, Nick and Vanessa hit Aguilera’s party, then slid over to Chateau Marmont for a late-night scene.
