Lindsay Lohan and her British Boytoy Calum Best are enjoying a romantic Caribbean holiday together.

They didn’t seem shy as they kissed and “canoodled” on the beach and, Lindsay had a little nipple slip when soaking up the sun.

Lindsay Lohan finished rehab a few weeks ago, but she’s been seen going out pretty much every night since.

She was out partying at Les Deux Wednesday night in Hollywood wearing a sheer top with no bra on, and even with the terrible lighting conditions that thing is see-through.
