The picture of Orlando Bloom's past and present lovers was uploaded with the caption, "Fun with the stunning @mirandakerr & @katyperry #RiseAndSmize,".
An eyewitness told E! News that there are no hard feelings between the pair.
"Miranda came backstage and she went straight to the makeup chairs where Katy was hanging out and she greeted Katy with a hug," an eyewitness told E! News. "They took selfies together and chatted like best friends for at least 10 minutes before Katy left."
The pair split in 2014 and share son Flynn together. Kerr is says that she is now happier than ever with long term partner, Snapchat founder, Evan Spiegel.
The 33-year old Aussie supermodel recently revealed she battled depression following her split from the 39-year-old Pirates of the Caribbean star.
“After Orlando and I separated, I went through quite a bit of depression, and she made this remedy for me, and it’s now part of my range, called the Heart Chakra Essence,” she revealed in an interview with Byrdie.
