The pair, who were first linked at the Coachella Music Festival in 2011, split in January after nine months of dating, but apparently the young stars have had a change of heart.
"They are back together," a source reveals exclusively to E! News. "Ultimately they enjoy spending time together and they wanted to give it another shot. They make each other laugh and they are both very supportive of one another's successes."
Emma, 21, and Chord, 23, reunited two weeks ago and have been inseparable ever since.
This weekend they were spotting hanging out together in Venice, Calif., and on Sunday they were side-by-side at an Easter service in Beverly Hills.
The source adds, "They are now taking things day by day and having fun. Whether it lasts, we'll have to wait and see. They are not putting pressure on themselves to make it work."
