Hayden Panettiere's skimpy bikini has created an Internet buzz over the past few days as the actress shows off her body around Hawaii on a romantic getaway with her boyfriend, Scotty McKnight.

Panettiere was first snapped sporting a coral bikini while kissing the New York Jets player, who was wearing green swimming trunks.

The couple, who have been dating since June last year, exhibited full PDA as they spent the day on the beach. The 22-year-old Scream actress was seen grabbing her boyfriend from behind and kissing him passionately for most of the day.

On Sunday, the couple was spotted again this time playing tennis. Panettiere's photos became a hit online again after she was spotted playing in a skimpy brown bikini.

She's so competitive, a source at the Ritz-Carlton told Us Weekly. She wanted to beat Scotty on every stroke. If she missed, she was upset with herself, but then would laugh. And Scotty would run over to the net and kiss her.

Panettiere used her Twitter account to put up some pictures of her own. Lovin Hawaii with my man, she tweeted under a picture of her lying with her legs over McKnight, while rocking on a hammock.

On the same day Panettiere was spotted again in a bikini, this time playing with a basketball.

Panettiere, a longtime animal rights activist, was in Hawaii to volunteer on behalf of the Pacific Whale Foundation, according to US weekly.

She was introduced to McKnight by a mutual friend last year, and has been happily dating ever since. I'm a huge Jets fan and became very good friends with Mark [Sanchez] and his buddies, the actress told US Weekly last year. I've always been that girl who has a lot of dude friends. I'm into sports so we have a lot in common.

Panettiere is not the only celebrity to be snapped playing sports in a bikini. Jennifer Love Hewitt was previously snapped playing tennis in a black two-piece and wedges.
