But on Thursday Dobrev got in some gal pal time for a day at the beach with model and surfer, Ivy Miller. 

The Vampire Diaries star shared a couple of photos of the pair showing off their toned figures in bikinis while proudly holding their surfboards.

Flashing a big beaming smile, the Bulgarian-born star stunned in a mixed, two-piece that consisted of white bottoms and a black top.

She wore her dark brown tresses long and with a part on the left. 

Miller looked radiant as she showed off her tanned figure in a black bikini. 

Feeling flirty, Dobrev teased her 20.4 million followers when she and Miller flaunted their derrieres by posing at a side-angle in a second photo, all while they still held on to their surfboards.

Later in the day The Perks of Being a Wallflower star got a special delivery, in the form of an ice-chest full of ice cream.

In a quick video she shared on her Insta-Story, Dobrev opened the container and pulled out the pints of ice cream one-by-one, and put them into her freezer.

‘Elsa from Frozen in real life #IceQueen,’ she wrote, in reference to the blockbuster Disney film, at the bottom of one of the clips.
