Hayden Panettiere & Wladimir Klitschko -- Bikini Makeout Time!

After recently getting back together, Hayden Panettiere and her giant boyfriend Wladimir Klitschko continued on their face sucking PDA tour by soaking up the sun -- and each other -- on the beach in Hollywood, Florida on Tuesday.

With rumors speculating they are already engaged, a ringless Hayden showed off her lady curves in a sexy purple fringe bikini, while Wlad bronzed his jacked up boxer's physique by going shirtless.
