The actress, 51, hit up Jennifer Aniston and Justin Theroux's surprise backyard wedding just a few weeks ago with Randall, 49, on her arm, but the secret ceremony wasn't the first outing for the new couple. A source told PEOPLE the pair have been dating for "several months."
Randall (who previously dated Paris St. John, 23, the daughter of The Young and the Restless actor Kristoff St. John) even attended Bullock's July 4 party at her home in Austin, Texas, where he met some of her friends, including Aniston and Theroux.
Randall and Bullock – who divorced husband Jesse James in 2010 after five years of marriage – make one attractive couple. The talented photographer was once a high-fashion model. Here's more on that, and a few other things to know about Randall.
1. He runs a successful lifestyle photography company.
Randall works as a professional photographer, mainly in L.A. He's been based there for about nine years, running Bryan Randall Photography. The pro seems to focus on photographing children and outdoor scenes.
Randall is also partnered with The Actor's Company, taking head shots for rising and aspiring stars.
"He brings his artistic instinct and compassion for actors to every shot he takes, which is why he is one of the most hard-working and sought-after photographers in this town," the site says.
2. He's modeled for Harper's Bazaar and Saint Laurent.
Prior to delving into photography, Randall worked as a high-fashion model throughout the 1990s. Online portfolios show images of Randall posing in menswear for fashion house Saint Laurent and, in another, smoldering behind sunglasses.
In 2011, Randall posed alongside Cindy Crawford for a spread in Harper's Bazaar Singapore.

3. Randall has studied acting.
The photographer once attended the popular L.A. drama school Anthony Meindl's Actor Workshop. Some of the screenwriter and actor's former students include Jenna Dewan Tatum and Shailene Woodley.
4. He has a daughter.
Like Bullock, who dotes on her 5-year-old son Louis, Randall is the proud dad to a college-aged daughter and comes from a close-knit family. "He's a great guy and had a great family life growing up," a family friend told PEOPLE in this week's issue. "His parents are amazing people. Everyone is really proud of him for being a talented photographer and model."
5. He's originally from Portland, Oregon.
The Californian actually hails from a bit farther up the West Coast – Portland! Randall's relationship with Bullock has been the "word on the Portland streets," a source told PEOPLE. "Everyone thinks it's great he's dating [Bullock]."
