Kelly and Sharon Osbourne are the latest stars to collaborate with Mac Cosmetics on a colour makeup collection and naturally, the launch of their first line was never going to be quiet.
The mother and daughter have been in London with the brand to reveal their products and with a busy schedule of photocalls and presentations in Mac stores and Selfridges, the past 24 hours have been non-stop for the pair.
However, these pictures from their day out prove it was nothing but a laugh a minute...

Kelly looked radiant in a chic LBD and made a good case for buying a colour-popping lipstick this summer. (In case you were wondering, her Mac collection includes a brilliant bright purple shade called Dodgy Girl.)
Sharon kept her press launch style smart and simple in a black suit paired with metallic stilettos.
And speaking of having a blast, we're not entirely sure what sparked this fit of giggles but it might have had something to do with the jacket swap (you probably had to be there...)

Kelly's day wasn't all makeup, makeup, makeup though. Later on in the evening, she stopped by The Arts Club in Mayfair to watch Dionne Warwick in concert. Oh, and she bumped into Nicole Scherzinger too, who was dressed down in a check shirt and skinny jeans.
Is that fabulous red shade one of Kelly's new lipsticks, Nicole?
