They love nothing more than spending time together, and although Zac’s friends are always trying to get him to party with them, he prefers to have romantic nights in with his girlfriend.

“He says he’s honoured to be with her,” one of Zac’s friends revealed. “He thinks she’s just amazing. They’re like an old married couple.”

Zac, 22, and 21-year-old Vanessa have repeatedly denied claims they are planning to tie the knot, although Vanessa has been heard discussing her dream engagement ring with pals.

Zac has reportedly told pals he is coming round to the idea of marriage, and would love to have the ceremony on the beach in Malibu. “Zac says when he looks at his life, there’s no way he can envision it without Vanessa,” a source explained.
