The 40-year-old actor and the 29-year-old model were photographed enjoying a romantic getaway on Italy's Amalfi Coast at the Tre Ville luxury hotel residence last week, where the smokin' hot couple couldn't keep their hands off each other as they soaked up the sun on the beach.
Shayk flaunted her sexy model bod in a tiny two-piece bikini while Cooper rocked orange swim trunks as the two strolled barefoot in the sand.
A source tells E! News that the good-looking couple, who were first romantically linked in May, have been relaxing and having fun together while they both had a few days off.
We're told the duo have been keeping a low profile over the past few months, which is why we haven't seen them out and about—although the two have gotten very close and, as is evident by the PDA pics, the pair have a crazy attraction.
Additionally, the insider reveals that the two laugh all the time, have a lot in common and enjoy very similar activities, including dancing, traveling and going to museums.
The source adds that the two, who have yet to publicly discuss their romance, are getting serious and are loving every moment they spend getting to know each other.
Furthermore, a second source tells E! News that the lovebirds have been seen walking around and sightseeing in the picturesque town of Positano.
"They looked very happy and flirty with each other," says an eyewitness. "And certainly very, very taken with each other. They couldn't keep their hands off each other."
We can tell!
