A friend with a big mouth just spilled some major royal beans! Prince William is allegedly going to marry his longtime love, Kate Middleton, in June 2012, right after his 30th birthday. The couple’s friend, Jules Knight of the band, Blake, told British magazine The People that William would like to focus on his military duties as a RAF pilot for the next three years and Kate supports that plan. “She’s mentioned Blake might be able to perform at the wedding, which would be brilliant for us,” Knight told People. Hmm, maybe not after you told a gossip mag their secret wedding plans, dude.
