Christa B. Allen is officially 30...and flirty...and, well, you know the rest!

On Thursday, Nov. 11, the actress well-known for playing Jennifer Garner's younger self in the beloved 2004 rom-com 13 Going on 30 officially celebrated her own 30th birthday. And from the looks of her birthday celebrations so far—chronicled on social media, of course—Allen is certainly thriving. The actress, who also starred on Revenge, got dressed up in a glittering gold gown and headed out for a special dinner on Wednesday night at Shoku in Los Angeles to ring in her milestone birthday with loved ones.
