No, he's not.
HC, I think that you're right. Mark Webber is 37 (I think) and Ann Neal, his partner, is 13 years older than him. She's got a grown-up child from a previous relationship but she and Mark have been partners for many years now, from back when he racing in Formula 3 in the UK, I think.
That's true, but Maria Sharapova is not Mark Webber's partner.
