Hollywood actress Jennifer Lawrence has sparked speculation she is to tie the knot with her boyfriend Nicholas Hoult after she was spotted wearing an elaborate ring on her wedding finger.

The Hunger Games actress has been dating the Brit on and off since 2011 after meeting him on the set of superhero movie X-Men: First Class.

The couple is now rumoured to be planning a wedding after Lawrence was seen sporting a large turquoise gem on her ring finger while enjoying a drink with her partner outside an Italian restaurant in north London on Thursday (24Apr14).

She was also photographed wearing the ring later that evening following dinner with Hoult at the British capital's Chiltern Firehouse hotspot.
