What: The girls flaunt their party frocks to celebrate the celebrity agent Jonathan Shalit's birthday. Tulisa does cleavage-flashing (in the manner of Kelly Brook) in a sparkling LBD, while Brook kind of covers up in a figure-hugging printed mini dress. Role reversal or what?
Where: The V&A Museum in London, 17 April.
Bonus info: Kelly Brook, last we heard, you were in the Algarve. Where's your tan gone?
