Reese Witherspoon's little girl is all grown up! The "Legally Blonde" star's daughter, Ava Phillippe, turned 22 on Thursday and Reese can barely believe how much she's grown. "Happy Birthday to my sweet little girl…excuse me… I mean my adult daughter!!! Words can't describe how proud I am of you," she wrote on Instagram. Reese shares two children, Ava, and 17-year-old Deacon, with her ex-husband Ryan Phillippe. The "Morning Show" star was 22 years old when she had Ava.
