What a precious mother-son moment!
Reese Witherspoon took to Instagram on Sunday, Jan. 3 to share a sweet snapshot of herself and her three-year-old son Tennessee — and we can't get over over how big the actress' little boy has gotten!
"Last day of vacation! 💖," the 39-year-old Legally Blonde star captioned the adorable photo of the two swimming on a family getaway.
Reese and her hubby, Jim Toth — whom she tied the knot with in 2011 — welcomed Tennessee in September 2012. The actress is also a mom to daughter Ava, 16, and son Deacon, 11, from her first marriage to actor Ryan Phillippe.
