Justin Timberlake & Jessica Biel back on?

On-off couple very much back together for night out in NYC

They may have officially ended their four year romance back in March, but it seems Jessica Biel and Justin Timberlake just can't shake each other loose. The former lovers looked every inch the happy couple as they attended a party at Justin's restaurant, Southern Hospitality, in New York City.

Looking happy and relaxed the exes cosied up to each other at the Neuro Hosts One Night Only party, which was also attended by Elton John and David Furnish, igniting reconciliation rumours again.

Jessica, 29, and Justin, 30, have been spotted on several occasions since their low-key romance ended in March, making them one of Hollywood's most on/off 'lets just see where this goes' couples.

During the separation both were reportedly dating other Hollywood elite, she was rumoured to be dating Bradley Cooper and Gerard Butler (us, jealous?) while he has been linked to Friends With Benefits co-star Mila Kunis and Scarlett Johansson.

We won't hold our breath, but maybe this time...
