Chord Overstreet and Emma Roberts "were having so much fun together" over Easter weekend.
The couple split back in January after meeting at Coachella music festival in April 2011.
Chord and Emma rekindled their relationship recently and decided to spend Saturday night at Pinz bowling alley in Los Angeles.
"They were having so much fun together and Emma even took photos of Chord with a female fan," an eyewitness told Radar Online.
Chord and Emma were indubitably into each other.
"They were laughing and giggling and hugging each other, just like a normal couple," the source detailed.
The pair acted as each other's cheerleaders.
"Chord and Emma cheered each other on as they hit the pins," the source added.
Emma, 21, and Chord, 23, were also spotted attending Easter mass at a church in Beverly Hills on Sunday.
Before their split in January, the couple had been seeing each other for nine months.
