Doting mom Reese Witherspoon has a heartwarming wish for son Deacon on his 15th birthday. The Academy award-winning actor shared the sweet tribute on Instagram. Alongside a picture, in which she poses with her 'creative, kind, talented boy', the proud mama wrote, 'Happy Birthday to my wonderful, creative, kind, talented boy @deaconphillippe! Every day you teach me something new about beats, Fort Nite dances, fantasy football and cool sneakers.'

'What a gift to be your mom. I love you, buddy! (P.S. When did you get so tall!?) #Thisis15,' the actor added. The 'Big Little Lies' star shares Deacon and daughter Ava Elizabeth, 18 with ex-husband Ryan Phillippe.
