That was on May 20, which according to Robert's confirmation, would be 'a few months ago.'
Two important things though: Some say the ring Pearl is wearing in these snaps is not her engagement ring and was really just to put people off. Also, Pearl has since deleted the picture with Robert. This was done after he made the announcement confirming they had split.
Robert, who never, like never, speaks about his private life, said he broke his silence to "own the space." He also said he and Pearl are cool. There must be another reason she deleted all the snaps then... either way, maybe we'll get some pics of them together soon and we'll never know if it's them getting back together, if it was just a "great photo-op" or someone likes playing a game.
