Valentine's Day is coming to London! Of course the romantic day will be celebrated everywhere, but the film that features Ashton Kutcher, Julia Roberts, Jessica Biel, Taylor Lautner and Jessica Alba will be premiering in London tomorrow.

And to get ready for the event tomorrow, London's airports are being graced by Hollywood's A-Listers.

Jess Alba was one of the first to arrive at Heathrow and has since been seen dining out in some of London's finest eateries.

Ashton Kutcher who was seen at LAX airport is flying over the pond with his missus, Demi Moore and so is Emma Roberts who was also spotted at the airport.

The other stars of the film, including Taylor Lautner, Julia Roberts, Jessica Biel, Jennifer Garner, Bradley Cooper, Hector Elizondo and Topher Grace all better get a wriggle on and get over here sharpish.

Make sure you check back here tomorrow to see all the latest pictures of whose wearing what and all the gossip from tonight's premiere.
