Beyonce Knowles had an intimate “I Am…” tour after-party, which took place at indigO2, following her own show at London’s O2 Arena this week.

Rihanna and Beyonce’s hubby Jay-Z, were both spotted at the after-tour party. Beyonce used the event to introduce little sister Solange, who performed several songs from latest album, ‘SoL-AngeL and The Hadley St. Dreams’.

It looks like it’s time to start putting together a “Beyonce’s Obsession – Balmain” post, because this girl can’t get enough of Christophe Decarnin’s designs.

On this occasion Bey wore a Balmain studded mini skirt, from the Spring 2009 collection, with a silver tank.

I love the look, but I would also like to see Bey wearing other designers before her look starts to becomes stale, and predictable.

I’m sure many of you will say she’s already stale and predictable.
