One famously wore £3.2 million worth of diamonds to the Golden Globes this year, while the other is only just making a name for himself as a dancer.
But that didn't stop Jennifer Lopez and her new toyboy shopping at the same place yesterday.
The American Idol judge - estimated to be worth £96 million - and Casper Smart were pictured heading into the exclusive Polacheck's jewellery store in Calabasas, Los Angeles.
Casper, 24, exited first, making his way to Jen's white Bentley which he drove to a rear exit to pick up his 42-year-old girlfriend.
She jumped in the passenger seat and the pair sped off.
