Following sister Beyonce's wedding to long-time boyfriend Jay-Z last Friday, Solange Knowles was seen leaving the Bloomberg Tower Building in Manhattan on Saturday looking very busy!

21 year old Solange has a new album coming out this year entitled Soul Angel and the Hadley Street Dreams, and her new single I Decided has just been posted on her MySpace page. On top of that she is promoting another project, Baby Jamz, a range of toys for small children which features Hip-Hop inspired nursery rhymes.

She certainly looked like a high flyer wearing a black puff sleeved jacket, black skinny jeans, a Christian Dior belt and electric blue courts.

I keep seein celebs wearing electric and royal blue lately. It seems like it may be another trend right now!
