Katie Holmes and Jamie Foxx, who've been at the center of romance rumors for years, recently let their reticence go during a beach weekend and packed on the PDA.

“They were totally engaged with each other,” an onlooker told the magazine. “They were never on their phones. She had this incredible smile on her face. She looked smitten.”

The source added that the couple finished a bottle of champagne before kissing while watching the sunset. And their apparent boldness was a marked departure from their usual strategy of hiding away from prying eyes and cameras.

“Katie and Jamie care about each other a lot and they tried to stay as quiet as possible because they didn’t want to ruin that,” another source said. “They knew the second they stepped out together, it would open the gates for criticism.”

And after dating for five years in secret, the source added “they got to know each other and see where they were headed.”

Still, the source added that Holmes' friends remain worried she's entering into a relationship that leads to a dead end.

“No one can understand why Katie loves a man who can’t seem to commit,” the source said. “Everyone wants Katie to take care of herself.”
