Kellan Lutz's girlfriend Sharni Vinson reveals her incredibly thin bikini body


She's making a splash in Hollywood, through both her film work and burgeoning relationship with Breaking Dawn star Kellan Lutz, but Sharni Vinson was creating literal ripples over the weekend.
Not big ones, mind, as the 28-year-old actress is so slight she barely disturbed the surf in her native Sydney on Saturday as she enjoyed the Australian sun. 
Sharni, who starred as Cassie Turner in popular Australian soap Home and Away, is so thin you can see her ribcage in the pretty floral number.
