Jessica Biel was all smiles at last night's London film premiere of Easy Virtue - until she was asked about boyfriend Justin Timberlake.
The I Now Pronounce You Chuck & Larry star brought lashings of Hollywood glamour to a wed and windy London as she posed with co-stars Colin Firth and Ben Barnes to promote her latest flick.
But her sunny demeanor took a hit at the slightest mention of a certain JT.
The couple are rumoured to be engaged but are yet to confirm they will be taking a trip down the aisle yet.
Let's hope there isn't trouble in paradise.
