Celebrities change partners as often as they do their haircuts! In today and gone tomorrow!

Here are some Celebrity Pairs You Totally Forgot About:

1.  John Stamos and Carrie Ann Inaba.  This was back in the early ’90s, when she was a Fly Girl on “In Living Color”.

2.  Robert Downey Jr. and Sarah Jessica Parker.  They were together for seven years, from 1984 to 1991.

3.  Nick Lachey and Kim Kardashian.  They were linked in 2006, but Nick says they only went to a movie.

4.  Ryan Reynolds and Alanis Morissette.  They met at Drew Barrymore’s birthday party in 2002.  They eventually got engaged, but broke up in 2007.
