Jessica Alba & Nicole Richie's Mr Chow Reception Night
The cute couples joined fellow celebrities including Samantha and Charlotte Ronson, as well as Rachel Zoe, for the wedding reception of celebrity and fashion photographer and director Justin Coit and his bride Katherine Power.
Dressed in a bosom baring turquoise dress overtop her baby bump, Miss Alba held onto her suit-wearing husband as she jokingly tweeted, "Wearing high heels for more than an hour tonight let's just hope I don't get pregnant!"
Sending her congrats, the expecting actress later wrote, "Amazing & beautiful couple @justincoit & @KatherinePower we had an incredible nt celebrating ur everlasting love. Xo"
Meanwhile, Miss Richie opted for an ensemble consisting of a satin navy frock with strappy black heels and a tiara as she and her well-dressed Good Charlotte rocker beau made their grand entrance.
Nicole also made sure to tweet her blessings to the newlyweds, as she wrote, "Congratulations to the new married couple Mr. & Mrs. Coit! @justincoit @KatherinePower"
