Will the third time be the charm for Josh Brolin? According to an exclusive report in Us Weekly, a rep for the twice-divorced actor confirms he is engaged to his assistant, Kathryn Boyd.

An “insider close to Boyd”; told Us Weekly that Josh proposed to Kathryn last month, and the pair were apparently observed celebrating in Mexico recently.

“They were with two tables worth of people so it was a big group, more than eight people,”; an observer claims. “They had a fixed menu and it seemed like they were celebrating something… It looked like a party and it seemed celebratory.”;

The eyewitness also tells Us that the pair were “all over each other,”; adding that Kathryn was “sitting on his lap”; throughout dinner. “They were kissing each other a lot, had their arms around each other. Super affectionate all night.”;

Josh and Kathryn first began dating in March 2013, one month after reps for the actor and ex-wife Diane Lane announced they were getting divorced after eight years of marriage.

This will be the actor’s third marriage. In addition to Lane, he was previously married to Alice Adair, with whom he shares two children: 26-year-old Trevor and 20-year-old Eden. He and Lane had not children.
