There's been some activity on the celebrity relationship front.

It's all over for Jennifer Aniston and Vince Vaughn.

Rumors abound that the difference in height was the reason.

Nicole Richie and Brody Jenner are no more.

Apparently no one wants either of them.

Eva Longoria and Tony Parker are still together.

That's subject to change by the hour.

Jessica Simpson is back with John Mayer.

That was as of last Wednesday, when Mayer saw her with Romeo Antonio, and she immediately went to a room with Mayer.

I guess Romeo isn't much of a Romeo.

And a week can't go by without Lindsay Lohan falling in love with whomever.

Now it's Keanu Reeves seen here showing off the results of his two-week fried sushi diet.
