AnnaLynne McCord marked her 22nd birthday this weekend with a action-packed day out at the beach with her two sisters, Angel and Rachel.

Showing off her fabulous figure in two different pink bikinis, the energetic 90210 star joined her sisters – who also looked stunning in their bright two-pieces - for a sprint along the sand.

Next up was a girls vs. boys game of paddle tennis.

Despite the sporty sibling rivalry, the sisters stopped to hug and kiss each other each time their team won a point.

There was brief drama when Angel was hit by a canoe and had to be dragged out of the sea by pals.

AnnaLynne rushed to her sister's side but we're happy to report the accident wasn't serious and the beach party continued.
