After partying with Duffy in LA at the Grammys on Sunday, Cheryl Cole arrived back at Heathrow Airport yesterday. Simon Cowell is keen to sort out a visa so Cheryl can work in the States, and even Paris Hilton wants to see Cheryl make the move over the Atlantic, telling Heat magazine: "She's stunning and I bet they'll love her in the States". Cheryl will be heading overseas again very soon, but this time it's for Comic Relief as she'll be taking part in the charity climb up Mount Kilimanjaro in Africa. The slim singer has been told to bulk up for the trek, and has already put on weight in preparation. She still looks pretty tiny to me!
