Vanessa Minnillo has officially changed her name to Vanessa Lachey.

The TV presenter - who tied the knot with husband Nick Lachey in a surprise ceremony on Necker Island in the Caribbean in July - took to her twitter account to declare her new surname, and her Wikipedia page has also been updated to reflect the change.

The 31-year-old beauty tweeted: "So...I'm making it official, and I LOVE my "new name"! @VanessaLachey...has a nice ring to it ;) (sic)"

Her new twitter bio now reads: "Host by day, Wifey by night, Wanna-be Mommy all the time. (sic)"

The couple recently bough a Spanish-style property together in San Fernando Valley, Encino, California, which contains 18 rooms, including eight bathrooms, a swimming pool and several fireplaces.

Their purchase sparked rumours about the pair wanting children, but Vanessa has previously explained they are in no rush.

When asked about having kids, she replied: "Let's do it one chapter at a time, why rush? We have the rest of our lives. If you have children, once they're there, they're there. You can't say, 'I don't think I want to deal with you today.' No, they're there!"
