Avril Lavigne showed off her “Green Bikini” body around the sea of Cortez in Mexico

Lavigne was back on the beach again yesterday and slipped into a skimpy green bikini of her own design before joining her friends for a spot of snorkelling.

Leaving her luxury yacht for a smaller dingy, Avril donned a snorkelling mask before diving in.

She proved the perfect advert for her green bikini, which is from her own clothing range, Abbey Dawn and costs $50.
