Actress Susan Sarandon joined in on the trend of photobombing fellow Hollywood stars, sneaking in behind the cast of "Straight Outta Compton" as they took a group photo on the red carpet at the Screen Actors Guild Awards Saturday evening.

The actress pulled off a wide-eyed, open-mouthed pose while standing beside stars Corey Hawkins, Jason Mitchell, Neil Brown Jr., Aldis Hodge and O'Shea Jackson Jr.

"Straight Outta Compton" was up for the Outstanding Performance by a Cast in a Motion Picture award, but lost out to "Spotlight," according to the Huffington Post.

Meanwhile, Sarandon - accompanied by her daughter Eva Amurri and son Jack Robbins, according to Pop Sugar - was nomiated for her role in "The Secret Life of Marilyn Monroe" for Outstanding Performance by a Female Actor in a Television Movie or Miniseries, but lost out to Queen Latifah for "Bessie."

Sarandon also presented the in memoriam segment of the show, but faced a public backlash for wearing an outfit with very low-cut cleavage for the occasion, the Daily Mail U.K. reported.
