Selena is celebrating her birthday

Selena Gomez is rocking a sultry new hairdo.

The singer, who celebrates her 22nd birthday today, looked pretty with gentle waves in her locks as she posed for a selfie yesterday.

‘Ocean hair,’ Selena captioned the picture on Instagram.

It comes after Selena was spotted playing in the sea with model pal Cara Delevingne in Saint-Tropez on Monday.

Justin Bieber‘s on-off girlfriend headed out on a yacht with Cara, 21, before the friends took a dip together.

Selena also posted a photo of the duo larking about in front of a helicopter.
