Geri Halliwell is wasting no time to have a name change following her recent wedding to F1 boss Christian Horner. The newlyweds are currently enjoying a honeymoon in Monaco, but reports have been mounting that she has adopted his last name.

While the 42-year-old's handles on the social media sites are still @gerihalliwell and @therealgerihalliwell, she has changed her name on Twitter and Instagram to Geri Horner. The former Spice Girls singer referenced her name change on Instagram, writing: "new beginnings" on a picture showing the words "Mrs Horner" embroidered in blue thread.
