"David and Samantha looked well and truly back on track. He had his arm around her as they walked back through the crowd and she was giggling away," an eye witness said.
"Whatever has happened between them seems to have been resolved, and they seemed to be having a great time as they wandered around the louder lounge," added the eye witness.
Barks was seen in a pair of jeans with a crop black top, a khaki style waxed jacket, a pair of large sunglasses and a pair of blue and white boots.
Gandy meanwhile looked dapper in a pair of blue jeans with a leather jacket over a grey cardigan.
