Cameron Diaz and Justin TimberlakeSweetheart Justin Timberlake flew to London to deliver a present to his Valentine Cameron Diaz - but she’s been too busy to spend much time with him.

He bought Cameron an £850 Louis Vuitton bag from Beverley Hills but has hardly seen his girl because she’s working such long days on the Surrey set of her new film, The Holiday.

A source from their hotel told the Sun: “Justin has been taking [spa] treatments in the afternoon just to pass the time.”

“He looked really down as he sat eating alone.”

“Cameron’s been arriving back at 2am so it’s hardly been the romantic Valentine’s week Justin was planning.”

Note to Justin: call us! we’ll keep you company! we’ve very good conversationalists and all that!
