Paris Hilton River Viperi Maui bikini Hawaii

Talk about a hot couple!

Paris Hilton flaunted her tight bod in a pink bikini in Maui on Sunday, but she wasn't the only perfect 10 on the beach ... we couldn't take our eyes off her her gorgeous new boyfriend River Viiperi!

The heiress and the Spanish model also hit up the pool over the weekend, and they enjoyed a nice mellow evening yesterday. "Lovely Hawaiian dinner tonight at one of my favorite restaurants" P tweeted. "Now in bed watching Men In Black 3. Love this movie."

The two made their first public appearance at New York Fashion Week earlier this month, and since then they've gone to Magic Mountain and been out for several romantic dinner dates. Um, jealous!
