Mila Kunis and Justin Timberlake spent their Saturday shopping separately around Paris. The Friends With Benefits stars took a break and visited French boutiques after debuting their romantic comedy in both Moscow and Berlin earlier in the week. Justin was spotted at Hermès, while Mila stopped by several designer outposts, including Isabel Marant, Givenchy, Chanel, and Céline. Mila has been sporting a healthy glow during their overseas trip, which may be partly due to her rumored investment in a pricey new beauty treatment. Mila reportedly spent $7,000 on a Borba facial that uses rubies and diamonds to exfoliate! Meanwhile, Justin recently made a big purchase of his own, teaming with an advertising company to put up $35 million for an ownership stake in MySpace.
