SANDRA BULLOCK commits to a lifetime of happiness with BRYAN RANDALL.

After four years together, Sandra Bullock and photographer Bryan Randall have quietly taken the next step in their relationship

Sandra Bullock and Bryan Randall looked smitten. In a candid black-and-white picture the model-turned-photographer shared on his private Instagram page in December, he and his love of four years can be seen staring into each other’s eyes as Bryan prepares to blow out the candles on a big white cake frosted with the playful message “Happy Birthday Bry Bry.” “Thank you for an incredible birthday,” he captioned the post. “God I love you.”

The feeling is mutual. Life & Style has exclusively learned Sandra and Bryan are so in love, so happy and so committed that they’ve quietly taken a huge step in their relationship. “Sandra and Bryan are living like husband and wife because they are husband and wife,” reveals a source. “Word is they had a secret wedding ceremony, just them and the kids at her home in LA. There was no fanfare, no bridesmaids, no wedding planner. It’s what Sandra wanted — a simple ceremony for the only people that matter: Bryan, her son, Louis, and her daughter, Laila.” The celebration was — just like their romance that started after Sandra, 54, hired Bryan, 52, to photograph her son’s birthday party — incredibly “lowkey,” says the source. Sandra wore a pretty cream dress, Bryan donned a nice jacket and Louis, whom she brought home in 2010, and Laila, whom she adopted in 2015, wore their best party clothes. “A trusted friend of Bryan’s officiated: They said their vows, exchanged rings, kissed and he pronounced them husband and wife,” adds the source, noting that it’s un- clear whether the ceremony was legally binding — but that didn’t matter to the duo. “It was very emotional for them both.”

While a rep for Sandra denies the wedding took place, Bryan has been seen wearing his ring around LA. His bride keeps her finger bare in public. “She’s proud to be his one-and-only but doesn’t want any comparisons to her marriage to Jesse [James, 49],” explains the source of Sandra’s brutal 2010 divorce in the wake of the Monster Garage star’s heartbreaking cheat-

ing scandal. “What Jesse did still haunts her. That’s the reason she’s held off on marriage and why she’s still not ready to shout her love from the rooftops.”

So she and Bryan are continuing to do things their way. “Sandra and Bryan don’t need to prove their love and commitment to anyone but each other,” says the source. “She considers Bryan her life partner. He’s a good man, she can trust him, he’s loyal and he’s a solid father to her kids. That is all that matters to Sandra.”
