Justin Theroux and his ex Jennifer Aniston are forever the perfect example of how to remain amicable after a split! The 50-year-old actor paid tribute to his former wife in the cheekiest way possible to help celebrate her 53rd birthday on Friday (February 12). In a since-deleted Instagram post, Justin shared a clip of Jennifer rocking a sweater that read “I’m A Cool Blonde” as she lights up what appears to be a cigarette. He captioned the video, “Happy Birthday @jenniferaniston,” and “Yes you are. Love u B.”
