Given we're in the middle of MyDaily's own first birthday celebrations, we're always keen to see how other people celebrate theirs - Madonna and daughter Lourdes marked the year anniversary of their fashion brand Material Girl with a celebration attended by Lourdes and the brand's spokesmodel Kelly Osbourne. Madge herself was apparently AWOL but it looked like Kelly and Lola (for thus she is known) had plenty of fun without her.
Kelly Osbourne, who replaced Taylor Momsen as the face of the brand, matched the shoes but went for a darker look with a black pencil skirt, leopard print tee and biker jacket. Geek chic specs and candy pink lips rounded things off nicely.
And from the Material Girl twitter account: "What's a Material Girl Birthday PARTY without an AmAzZiNg cake?!!"
