Kate MossKate MossGosh, Kate Moss' luncheon diary is jolly jam-packed.

After stepping out to Mr Chows with new buddy Lindsay Lohan earlier this week, the stylish miss has now been seen scoffing ice cream with another fellow celeb.

Kate's currently hanging out in LA after recent modelling shoots took her to the beaches of the Caribbean.

And it seems she can't go 24 hours in La-La-land without bagging herself another star chum.

The latest mate for Kate is the newly slimmed-down Jack Osbourne, who joined the model for a spot of shopping.

And it seems trim Jack and equally trim Kate aren't adverse to a few calories now and again, as snappers caught the pair stopping off for some ice cream at the mall.

Jack OsbourneJack OsbourneJack is even pictured shovelling the sweet stuff into Kate's mouth.

The new friends have both been through a reinvention of late, and have both spent well-publicised stints in rehab.

Add this to their mutual love of a bit of tutti fruitti and it could be the start of a great friendship.
