Even though we're well into fall, Emma and Katy were very spring-y in their chosen ensembles, with the Voguecover girl in a crisp white blouse and ruffled silver skirt by Brock Collection, and the recent birthday girl in a lacy and frilly Rodarte number styled with black Tamara Mellon shoes.
Hey, when the weather is so warm, you might as well wear something light!
Meanwhile, Ciara and Demi were a little more autumnal in their outfits. Making her first public appearance since the pregnancy announcement, CiCi covered her growing baby bump in a black dress and navy blazer, while Dem kept it casual in black slacks and a red print tunic.
On Sunday night, Drake rang in his 30th birthday with a celeb-filled party at Delilah in West Hollywood — and among the guest list were exes John Mayer and Taylor Swift! Gasp!
According to TMZ, T. Swift hit up the El Lay hot spot alongside her girl squad members Karlie Kloss and the Haim sisters — while the Gravity singer arrived to the club solo looking dapper in a black suit.
We're hearing that not only was the Dear John songstress in attendance but, according to the photo agency who snapped the crooner's pic (above right), so was another one of Mayer's former loves… Katy Perry! Ah!
