They were #donezo.
However, over the weekend reports are now coming out that R.Patz isn't finding it too hard to move on.
Before you start thinking about a #Robsten reunion (we wish), it's with none other than Katy Perry!
According to sources, "Rob’s been talking and texting with Katy, and they’ve become super super close.
"There’s always been a really strong chemistry between them, and a definite attraction, but they’ve never acted on it, because all the time they’ve known each other one or other of them has been involved with someone else. However, now they’re both single, there’s no stopping them from taking it to the next level, although Rob wants to make sure he’s mentally in the right place before making any kind of move."
A few months ago, the two were actually spotted on a romantic dinner date together, while he was still with FKA Twigs.
The source continued: "There's no doubt that he's really into Katy, and that he fancies her like crazy, but, he's determined to not get in to some kind of rebound romance - herespects and cares about Katy way too much to risk blowing the friendship they currently have."
We guess we'll just have to wait and see.
