and her beau
, Austin Butler, were "all over each other" at the Fontainebleau Resort pool in Miami Thursday, an onlooker tells PEOPLE.
"They were so into each other it didn't seem to matter where they were," according to the source (and the photos don't lie, either!).
The couple partied with a group of friends on the resort's beach and went for a swim in the ocean, the eyewitness said.
Also having fun in the sun were Maria Menounos and her boyfriend, Kevin Undergaro, spotted playing football on the beach.
