The American singer - who is in London at the moment - and the British fashion designer went to see Bradley Cooper, Ed Helms and Zach Galifianakis` film `The Hangover` last year, and now they are preparing a trip to see the sequel in the US because it is "tradition". Jennifer said: "We saw `Hangover` together so now it is a tradition. So when I get back to LA we will go see it. " But the pair try to avoid being spotted when they take in films by dressing down for the occasion and using an alternative entrance. She added: "We go dressed down in sweats and sneakers. We sneak in through the kitchens." Their film date may have to happen before July, when Victoria is due to give birth to a daughter - a sister for the three sons, Brooklyn, 12, Romeo, eight, and six-year-old Cruz, she has with husband David Beckham - and Jennifer said the former Spice Girls star is "so excited" at her forthcoming arrival. Appearing on `Alan Carr: Chatty Man`, she told the host: "I saw Victoria the other week with the belly and she▓s so excited."
