Kathryn Boyd walked the Cannes red carpet with fiancé Josh Brolin, showing off her exquisite engagement ring, in their first appearance after news broke out two days ago. 

The engaged couple were at the 68th Cannes Film Festival to attend the premiere of Brolin's latest movie, Sicario. Besides the sparkling rock on her left hand, Boyd stunned everyone with her gorgeous look. 

The 28-year-old model wore an orange gown with ruffled detailing and a thigh-high slit, which elongated her legs. Brolin, on the other hand, looked dashing in his tuxedo. 

They held hands and shared kisses upon arriving at the red carpet event, according to Hello! Magazine 

US Weekly was the first to announce their engagement, through a confirmation from their representative, following a two-year romance. The couple allegedly had a party to celebrate the occasion at Cabo San Lucas, Mexico. 

Sources claim to have seen Boyd sitting on her fiancé's lap during dinner, and "were kissing each other a lot and had their arms around each other."

Boyd is undeniably a proud girlfriend as she posted a lot of pictures with Josh posted in her on her Instagram page. The couple looked loved-up, and even took a selfie inside the car before they headed to the Cannes event.   

The American Gangster actor and his former assistant, who is now soon-to-be Mrs. Brolin, started dating since March of 2013, a month after Brolin's ex-wife Diane Lane filed a divorce. They were married for eight years.

Not long after Brolin and Lane's divorce was finialized, Brolin with his new found love finally confirmed their relationship in May 2014.

The couple had received backlash since coming out in public, with people assuming that Boyd was behind Lane and Brolin's controversial break-up. However, they have put up a united front, and even looked sweeter in the months that followed.
