How time flies!
Uma Thurman shared a super rare photo with her son, Levon, on Thursday, Oct. 13 — and in case you didn't know, he's somehow already a teenager!
"#TBT South Hampton with my beautiful son, Levon! #Summer2016," the 46-year-old actress captioned the sweet snapshot of the two.
Uma and her ex-husband Ethan Hawke — they were married from 1998 until 2005 — previously welcomed Levon, 14, in January 2012. The former pair are also parents to a daughter, Maya, 18. The Pulp Fiction star is additionally a mom to a four-year-old daughter Luna from her previous relationship with Arpad Busson.
