'Friends' co-stars Matt LeBlanc and Courteney Cox share Matthew Perry memories

Matt LeBlanc and Courteney Cox paid tribute to their late "Friends" co-star Matthew Perry on Tuesday, with the former saying "the times we had together are honestly among the favorite times of my life."

It's been a little more than two weeks since Perry was found unresponsive in the hot tub of his Southern California home.

"It is with a heavy heart I say goodbye," LeBlanc wrote on Instagram, with a series of pictures from their "Friends" days.

LeBlanc added: "It was an honor to share the stage with you and to call you my friend. I will always smile when I think of you and I’ll never forget you. Never."

Perry had been open about his longtime struggles with substance abuse and LeBlanc appeared to make reference to that, saying his friend was finally "free."

"Spread your wings and fly brother you’re finally free," LeBlanc wrote. "Much love."

He sneaked in one final comedic jab, telling the world his on-screen roommate had the gall of skipping out on a $20 debt.

"And I guess you’re keeping the 20 bucks you owe me," LeBlanc quipped.

Cox also paid tribute on Instagram, writing: "I am so grateful for every moment I had with you Matty and I miss you every day.”

She shared a video of her and Perry filming a "Friends" scene that left the two in laughter, calling it "one of my favorites."

"To give a little backstory, Chandler and Monica were supposed to have a one night fling in London. But because of the audience’s reaction, it became the beginning of their love story," she wrote. "In this scene, before we started rolling, he whispered a funny line for me to say. He often did things like that. He was funny and he was kind."
