From their days of playing the Green sisters on Friends to their current roles as competitive co-workers on The Morning Show, Reese Witherspoon, 46, and Jennifer Aniston's friendship goes waaay back. So we weren't surprised to see that when Aniston's 54th birthday rolled around on Feb. 11, Witherspoon left her a loving tribute on Instagram.
“Happy Birthday @jenniferaniston!” the Legally Blonde star captioned a carousel of photos featuring her and Aniston through the years. “What a gift to get to work with my big sis everyday on @themorningshow. You always give the best advice and endless LOVE and support. I [love] you, Jen! Everyone wish her a Happy Birthday!!”
