The two were stars of the iconic Disney show Drake & Josh, and fans were quick to notice his absence, which led to Drake publicly tweeting his disappointment.
The posts which have now been deleted read:
""When you're not invited to the wedding, the message is clear.
"True colors have come out today. Message is loud and clear.
"loyalty is key. ALWAYS remember where you came from."
We're pretty devastated about the public break-up, and we hope Josh had a good reason for not inviting Drake :(
