Last September it was confirmed that she and her partner, Dave Gardner, were expecting their first child together - Liv's second.
Whilst Liv and Dave, David Beckham's best friend, have only been dating for a short time - they met in early 2014 through Kate Moss - insiders claim the couple are smitten and thrilled to be expecting a new addition to their family.
Their engagement joy has yet to be confirmed or denied by the star's rep, but if she is indeed engaged, this will be her second marriage. She famously married British musician Royston Langdon at a secret ceremony in Barbados, followed by an official do in New York (wearing none other than Alexander McQueen) back in 2003. They separated in 2008.
