Australian lingerie brand Berlei has launched a new sports bra campaign with Serena Williams as its brand ambassador.

The 22-time Grand Slam winner commented 'As a female athlete, I know how important a good bra is. As my tennis regime includes tons of high performances and exercises, I'm always running and bouncing and jumping, and I need to be confident there in both comfort and support - especially on court. I am excited to introduce these globally; I haven't looked back since my mum introduced me to Berlei'.
