AnnaLynne McCord's swimsuit looks like it could have come from the pages of Fifty Shades of Grey!

The 90210 star wore a tiny, bondage-inspired bikini Jan. 1 for a day at Sydney, Australia's Manly Beach with Dominic Purcell.

The gold rings and strappy ties on AnnaLynne's two-piece might leave some interesting tan lines, but the 26-year-old brunette beauty didn't look too concerned. She was all smiles on New Year's Day, holding hands with her 43-year-old Prison Break star beau (who didn't look too bad himself while wearing only a pair of swim trunks).
