The proof that these two are in good standing was clearly on display at the Teen Choice Awards, when Thorne and Posey cozied up for a photo together.
Who said exes can't be friends, right?
"Honestly, Ty and I stopped dating and that was really difficult for me...It was definitely one of the hardest breakups I've been through," the Freeform star admitted.
For Thorne — who was recently spotted out with Scott Disick in Cannes, but declared she was just a friend of the reality star — staying pals with one of her exes is, seemingly, no big deal. She recently shared a sweet birthday message to her ex-boyfriend Gregg Sulkin, whom she dated for one year.
"Happy birthday Gregg!!!! I love you :)) always been such a wonderful person:) glad we are here through thick and thin. Let's party you old man!!," the actress wrote on Instagram.
If only we could bottle up Thorne's chillness for anytime we saw an ex out in public.
