Pop Stars/Designer/Icons Diddy and Beyonce met up in Vegas yesterday showing off their newest lines at the MAGIC Fashion & Apparel Trade Show. Diddy looked particularly happy -- maybe he was still glowing from mining not only a band but a solo artist out of Making The Band 4! Triumph! (Though could they ever top Danity Kane??) Of course, Tina, the driving force behind House of Dereon, was in the house with her daughter and happy to pose. Among other celeb designers milling around: Rusell Simmons, LL Cool J and Travis Barker (check them out in the gallery below). Fun times.
