Justin Bieber celebrated rapper Sexyy Red’s 27th birthday with a kiss on the cheek, and fans quipped the singer “looks happier” with her than his wife, Hailey Bieber. The “Peaches” crooner took to Instagram Thursday to share a clip from the “U My Everything” hitmaker’s bash, which saw him embrace the latter and give her a warm smooch. He beamed while letting go of Sexyy Red, who laughed off the sweet interaction.

Several fans were thrilled to see Justin, 31, smiling, with some comparing his interaction with the “Get It Sexyy” rapper to how he seemingly appears with Hailey, 28.

“Why does he look happier with her than with Hailey ,” one person commented.

“I forgot he could smile,” another added, as a third chimed in, “Happiest I’ve seen you in a minute.”

Other fans, however, defended Hailey, with one writing, “When you get married (sic) its not always rainbows and butterflies (sic) god forbid the guy has fun every now and then.”

Another told critics that assumed marital issues between the Rhode founder and Justin were in their “own heads.”

Hailey, however, didn’t appear to be bothered by the video, as she wrote, “.”

Justin and Hailey tend to appear stoic while out on dates in Los Angeles, as paparazzi swarm them. The couple appeared bothered while entering and leaving Alba restaurant in West Hollywood on Tuesday. They also kept a low profile during a lunchtime outing the week before.

Justin, however, has caused concern regarding his seemingly odd behavior in public over the past few months. In February, the “Peaches” singer went viral after he was spotted smiling widely and swaying his body while attending Hailey’s Rhode pop-up store. Despite worry, his rep has continuously defended him, referring to stories about his well-being as inaccurate assumptions and slamming speculation that the pop star is on drugs.
