Loving it up in London, Ashton Kutcher and Mila Kunis sweetly held hands during a walk through the city on Sunday (May 19).

The "Oz The Great and Powerful" star wore an all-black outfi,t save for some crisp white sneakers, while her "That '70s Show" costar sported a light cardigan, khakis, and a backwards navy baseball cap.

In town for work, the 29-year-old actress is shooting her new film "Jupiter Ascending" with the Wachowski Siblings.

Costarring Channing Tatum, Sean Bean, and Eddie Redmayne, the sci-fi flick tells the story of a universe where humans are at the bottom of the evolutionary ladder. A young destitute human woman is targeted for assassination by the Queen of the Universe because her very existence threatens to end the Queen's reign.
