The 'Waterfalls' hitmaker was spotted holding hands with her new beau on Friday night (03.01.13) as he supported the girl band at a concert at the MGM in Las Vegas.
A source told Us Weekly magazine: ''They were so cute, stopping to take pictures with fans. He kept her close to him the whole time.''
Chilli, whose real name is Rozonda Thomas, also gave the star a special shout-out at the private party held for MGM employees, and even brought him onto the stage during the set.
The couple have only been seeing each other for a fortnight, but this is their second shot at love, having briefly dated a year ago.
Chilli and Wayne - who originally called things off because of their hectic schedules - have been friends for years and are excited about giving their relationship another chance.
An insider told the magazine: ''It has only been two weeks but they really like each other. They've been friends for years but there has always been this flirtation.
''Both of them had a hard time being single, so they love dating a friend and someone in the business. They make a really great couple.''
