New 90210 star Megalyn Echikunwoke makes a good first impression as she sizzles in a tie-dye bikini

Given that the cast of hit LA-based series 90210 is notorious for its outrageously good looks, any newcomer might be forgiven for feeling a little daunted at the prospect of filming a sexy beach scene.

But Megalyn Ecikunwoke looked cool as a cucumber, sauntering around the set yesterday in a teeny pink bikini that flaunted her rocking curves.

The actress is set to appear in season four as lead character Naomi Clark's (played by AnnaLynne McCord) new rival.
