Katie Holmes and Tom Cruise

TomKat is officially kaput, so it's time to look back on their years together, including all their awkward kisses.

From the side hug to the accidental cheek peck, Tom Cruise and Katie Holmes never quite mastered PDA for the paparazzi.

Tom Cruise and Katie Holmes divorcing

After five years of marriage, Holmes filed for divorce, seeking sole custody of their 6-year-old daughter, Suri. She is also asking for a "suitable amount" of child support. The couple married in an Italian castle in November 2006 after dating for one year. This was the first marriage for Holmes, 33, and the third for Cruise, who turns 50 on Tuesday. He was previously married to Mimi Rogers and Nicole Kidman, with whom he has two children, Isabella, 19, and Connor, 17.
