Jennifer Aniston and Justin Theroux are spending their holiday vacation in Mexico and they apparently are more in love than ever.

"Jennifer and Justin have been very affectionate, kissing and snuggling up to one another. She loves to sit with her arms around him and lean into him for kisses," a source told E! Online.

"They aren't shy about public displays of affection...they can't keep their hands off one another," the source added. "They seem very happy together and totally in love. They haven't spent a lot of time apart on this trip. Wherever she is, Justin is right next to her."
