Tom Cruise and Katie Holmes' wacky romance

In 2005, Hollywood mega-star Tom Cruise announced that he was dating former teen actress Katie Holmes. From there, the world was treated to a non-stop show of antics, like Tom Cruise jumping on Oprah's couch while declaring his love for Holmes, to Eiffel Tower proposals, purchased sonogram machines for a baby on the way, motorcycle rides across red carpets, and of course, sweeping declarations of love for one another. Within a year, the two were married in a castle in Italy and welcomed a daughter, Suri Cruise. For five years, as they battled non-stop tabloid rumors, Katie and Tom or "TomKat" were a staple of Hollywood tabloid culture. But on June 29, a lawyer for Holmes announced that the actress had filed for divorce. Take a look back at some of the most memorable moments in the couple's six year romance.

In the press, it appeared that Holmes and Cruise's romance went from 0-60 in seconds. Cruise had previously been dating actress Penelope Cruz after his divorces from actresses Mimi Rogers and Nicole Kidman. Holmes had been engaged to "American Pie" star Chris Klein, with whom she split just weeks before meeting Cruise. (AP2005)

Cruise and Holmes' relationship was initially dominated by over-the-top displays of love and affection, including red carpet kisses where Tom would dip Katie, and riding into his "War of the Worlds" premiere on a motorcycle. Many questioned the romance, largely due in part to such displays, which, at times, seemed staged, awkward and out of place. But despite any criticism in the press, both Cruise and Holmes continued to be all smiles at appearances together, with Katie gushing about how when she was a young girl, she dreamed of marrying Cruise.

In the fall of 2006, the superstar couple traveled to Italy to prep for a lavish wedding ceremony. Among the guests were Cruise's A-list pals including Will Smith and Jada Pinkett, Jennifer Lopez and Marc Anthony and David and Victoria Beckham.

Holmes seemed to quickly fall right into place with Cruise's two children Connor and Isabella, whom he adopted with second wife Nicole Kidman.
