Ashton Kutcher

Ashton Kutcher and Mila Kunis brought their PDA courtside last night to watch as the LA Lakers took on the Phoenix Suns at the Staples Center. The usually press-shy couple cuddled up and laughed during the game, which the home team won 91-85. It wasn't all overt affection for Mila and Ashton, though — at one point, they held up a piece of paper to share a private moment. Their night out comes in the middle of a fun week. Ashton turned 35 on Feb. 7, and tomorrow is, of course, Valentine's Day. Tonight, Mila will attend the LA debut of Oz The Great and Powerful — and we'll be LIVE from the premiere! The fun starts tonight at 9:30 p.m. EST/6:30 p.m. PST right here on POPSUGAR. Ashton is expected to attend as well.

Ashton and Mila were joined at last night's matchup by Will Ferrell, who stole the show dressed as an usher with the name tag "Ted Vagina." Rocking his Anchorman 2 beard, Will made headlines by escorting Shaquille O'Neal out of the stadium after a supposed infraction from Shaq.

The couple that plays together stays together, and the same seems to be true for these celebrity duos who work out together. Keeping fit is a high priority in Hollywood, and these celebrities definitely know how to go from significant other to workout buddy. Take a look at these couples who love to sweat as a pair, whether it's at the gym, on the hills, or on the road!

Mila Kunis and Ashton Kutcher were side by side for a stop at a Coffee Bean & Tea Leaf in LA yesterday. The couple snuck in some downtime together ahead of a big event. Ashton will debut his film jOBS to close out the Sundance Film Festival tonight in Park City, UT. As the end of the action draws near, be sure to check out all the highlights from the Sundace Film Festival so far. Mila's also been making waves for her own prospective new project. Mila reportedly expressed interest in starring in the film adaptation of 50 Shades of Grey.

Ashton Kutcher and Mila Kunis made a casual stop to pick up coffee and bagels in LA yesterday and this afternoon they took their dog for a walk. The couple recently returned from vacationing in Brazil, where they rang in the New Year together. Ashton and Mila had a dinner date with friends at Mr. Lam's restaurant in Rio de Janeiro over the weekend before heading home. The pair also spent Christmas out of town visiting Ashton's family in Iowa. It looks like Ashton and Mila are getting back to their normal routine and gearing up for work after enjoying holiday downtime together. Ashton's latest project, Jobs, is set to hit theaters in April, while Mila's Oz: The Great and Powerful comes to the big screen in March.

Ashton Kutcher and Mila Kunis had a romantic date night at Mr. Lam restaurant in Rio de Janeiro on Friday evening. They were accompanied by friends, and Ashton had his eye on Mila as they said goodbye after the night out. Ashton and Mila apparently got away to Brazil to celebrate New Year's together, following a Christmas with the Kutchers in Iowa.

New Year's and Christmas aren't the only holidays Ashton and Mila spent together. Over Thanksgiving, Ashton visited Mila in Rome, where she was on location, filming The Third Person. Although he is now relaxing and enjoying some downtime, Ashton is currently involved in legal matters on two fronts. At the end of last month, he officially filed for divorce from Demi Moore after a year of separation. Ashton's production company is also in the midst of a suit. A California judge recently approved Katalyst's intent to sue the California DMV for going back on their commitment to cooperate on a reality TV show.
