After a short "break," Kendall Jenner and Devin Booker seem to be back together and even happier than where they left off.

The supermodel and NBA star were spotted spending the July 4 holiday together in the Hamptons at Michael Rubin's iconic annual celebration. A source also present at the party told E! News,

"Kendall and Devin arrived at Michael's party together and were hanging out by each other's sides a majority of the night. They were with a group of friends but they weren't trying to hide that they were there together."

Although they took a break after hitting a rocky patch mid June, it seems the pair has worked through their "different lifestyles" in just a few short weeks.

The source added,

"Kendall was holding on to Devin's arm the majority of the night and they looked really cute. They both were hanging out at the bar taking shots of 818 Tequila and Devin was grabbing rosé for them to also drink. Kendall looked really happy and she was smiling and laughing at him throughout the night."

Before their trip to the Hamptons, the two were snapped sharing smiles together at the SoHo house in Malibu. At the time, an eye-witness told E! News that they had a "great energy," sayinf,

"They shared things on their phones. Kendall was looking up and smiling at Devin."

Just a month ago, the two said they "hope to make it work." Now, it seems, they've taken steps towards a happier, healthier relationship.
