Double happiness takes the limelight when celebrity couples accept sponsor's invitation

While many celebrities go out of their way to conceal a relationship, a handful of star lovebirds are happy to steal the spotlight.

There were some serious public displays of affection from Andy On Chi-kit and girlfriend Jennifer Tse Ting-ting at the opening of a Van Cleef & Arpels shop earlier this month. The couple have been seen at the same event plenty of times before, including a promotion for McDonald's weddings in March when On happily gobbled down a burger fed to him by Tse.

Others who like to flaunt their happy togetherness around town include the model couples Jocelyn Luko and Anthony Sandstrom, Jessica Cambensy and Sergio Bochert, and Mikki Yao and Sunny Tsang.

One thing for sure is that it's a win-win situation. For an event's hosts, the celebrity couples attract more press publicity. And of course the celebs don't mind smiling for the cameras when they can both walk away with a pay cheque at the end of the evening.
