AceShowbiz - Tamar Braxton reunited with ex-husband Vincent Herbert for their son's graduation, but something didn't feel right. This is because the 46-year-old Streamline Records founder looked less than thrilled when posing for photos with the "Braxton Family Values" star during the ceremony that took place on Saturday, May 18.

In several photos that Tamar shared on Instagram, the winner of "Celebrity Big Brother", along with her son Logan and her mother Evelyn, could be seen flashing a smile outside of the school building. The 5-year-old was even striking a playful pose in one of the photos. Vincent, on the other hands, did not smile at all. He was frowning instead.

This made her followers speculate what caused Vincent to look like that during the happy occasion, with some suggesting that Tamar's boyfriend, David Adefeso, might be the one taking the pictures. "I would have Diddy cropped Vince out. Is Tamar Man taking the pic or something cause Vince is about to lose it. His dad looks like he doesn't want to be there. Vince has to be a new meme. Daddy shark-a-doo isn't with it. Vince face expression says it all," one said.

Someone else echoed, "Is David taking the pic because Vince looking real mad," while one other asked, "Why Vince mean muggin and everyone else is FULL of JOY??" Another joked, "Why Vince look like the kid someone forced to take a photo?" There were also people who urged Tamar to crop Vince out of the pictures because he "ruined the mood."

Tamar filed for divorce from Vincent in October 2017 after nine years of marriage. Recently, the "All the Way Home" singer asked judges to allow her single status to be restored while the pair finalize their divorce, allowing them to sort finances, custody and other arrangements at a later date.
