A formerly rumored and private love affair became public this weekend when actor Bradley Cooper and his reported model girlfriend, Suki Waterhouse, stepped out together to attend the 2013 Spike TV’s Guys Choice Awards on Saturday.

Backstage photographers captured Bradley’s rumored girlfriend socializing alongside the 38-year-old actor with Oscar-award nominee Amy Adams, “Ted” star Mark Wahlberg and Spike TV’s “Guy of the Year” Ben Affleck, among others. Yahoo reported Monday that the actor was also seen holding hands and cuddling backstage with Waterhouse, 20, at the Culver City, Calif., event.

When "The Hangover Part III" star was not enjoying the awards show with his newfound love, photographers also spotted the actor alongside “We’re the Millers" star and his rumored 2009 love interest, Jennifer Aniston. Eye witnesses claimed Waterhouse smiled politely upon leaving the ceremony at Sony Pictures Studios as Cooper was reportedly asked to pose with enlisted ladies.

Waterhouse was first spotted with Cooper, People’s 2011 Sexiest Man Alive, in April, with photographers capturing the two walking in Paris. The duo also reportedly attended Elle’s Style Awards in February.

Despite the celebrity duo making their relationship official, Cooper was reportedly spotted with a mystery woman at the Tombs restaurant and saloon in Washington, D.C., last week, with the Washingtonian identifying the woman only as Alex. Witnesses claimed the actor was seen enjoying a romantic dinner in a private booth at the restaurant with the mystery female after attending the National Conference on Mental Health at the White House.

The 2013 Spike TV’s Guys Choice Awards show airs Wednesday at 9 p.m. ET.
