Khloé Kardashian Had a 'Cozy and Cuddly' Reunion with Odell Beckham Jr.: Source

Khloé Kardashian is single and ready to mingle. First man on her dance card? Odell Beckham Jr.

A source tells PEOPLE the Keeping up with the Kardashians star and the New York Giants wide receiver sparked this weekend at Scott Disick’s Las Vegas birthday party before getting very friendly at Drake’s beachside Memorial Day bash on Monday.

“They met in Vegas over the weekend for the first time and reconnected at Drake’s party where they hit it off,” says the source. “They were cozy and cuddly.”

Disick’s party at the Sin City outpost of 1 OAK came just two days after a KUWTK production source told PEOPLE that Kardashian, 31, was “very bubbly and happy” at Disick’s 33rd birthday dinner – just hours after she resumed divorce proceedings against estranged husband Lamar Odom, 35.

“Everyone in her family is happy that she is moving on,” the production source added of Kardashian’s decision to finalize the divorce. “She has all the support possible.”

Another KUWTK insider told PEOPLE on Thursday: “She wants to remove herself from the [Lamar] situation a bit. She wants to focus on her own happiness now.”

And what better to move on than with family by your side?

After Kardashian spent Friday night in Vegas with Disick, her older sister Kourtney and rapper Tyga (who is the ex of Kardashian’s younger sister Kylie Jenner), the former Kocktails with Khloé host made at an appearance at Drake’s party where Jenner, 18, was also getting cozy with a new guy.

“They were all over each other, kissing and making out,” a source told PEOPLE of Jenner and rapper PartyNextDoor. “It was almost like she was trying to make a statement.”
