Liv Tyler and David Gardner's baby boy, Sailor, is getting so big!
The 38-year-old actress' fiancé took to Instagram on Wednesday, Dec. 30 to share a cute new photo of their 10-month-old son learning how to play soccer from David's seven-year-old little boy, Grey.
"Serious [soccer] conversation happening... Big brother telling little brother all about the beautiful game!" David, 49, captioned the sweet snapshot of the lookalike siblings.
Liv and David — who had son Grey with his ex-wife in 2008 — began dating in 2014 and welcomed their son, Sailor, in February 2015. The Armageddon star is also a mom to an 11-year-old son, Milo, from her previous marriage to Royston Langdon.
