The couple has reunited after ending their two year relationship in January and confirmed their reconciliation when they arrived arm-in-arm for the Aug 17 bash, reports femalefirst.co.uk.
"They started the shoot in April as just friends and then one day they started kissing. One thing led to another and they hooked up. All her old feelings came rushing back. Jennifer has been telling people she's in love again," said a source.
