We Still Aren’t Over The Steamy PDA Photos Of Kristin Cavallari & Her New Boyfriend On Vacation–*Chills*

And the new couple did not shy away from any PDA.

The source added, "They were dancing, kissing hugging and just hanging out by the pool together."

"When the music came on, they got up and started to have a little dance party. Kristin was dirty dancing with Jeff and they couldn't keep their hands off each other. She seemed very happy and in a great mood," the witness explained before adding, "She grabbed Jeff and they pulled each other in for a long kiss. She was letting loose and clearly having a lot of fun."

Another source spoke to People that Cavallari "had a great weekend."

The insider explained, "Kristin had a great weekend in Cabo San Lucas. She was with friends and Jeff. Kristin and Jeff were very affectionate. She was beaming around him."

Although they definitely seem to be having fun getting to know each other, Kristin isn't looking for anything serious right now.

In October, a source told E!, "She's single, having fun and enjoying herself. She's single and can kiss whoever she wants."

With her busy schedule, Kristin also doesn't have a ton of time to date. Another insider told People in November: "[Kristin] is busy with her children and doesn't have much time to date. She enjoys spending time with Jeff, though."
