This is so sad.
Kellan Lutz and his skinny-mini girlfriend Sharni Vinson showed off their bikini bods yesterday in summery Sydney, Australia.
The Twilight hottie and new Tarzan lead is their to spend Christmas with Sharni's family, but before the real holiday festivities, the two were seen playing and flirting all day in the sand and waves.
Kellan and Sharni are definitely making us rethink those Christmas cupcakes!! LOLz!!
