Sean Penn and a Vibram FiveFingers shoe-wearing Scarlett Johansson took their love out on the road for a jog in LA yesterday. It wasn't a couples-only sweat session, though, as their mutual friend Owen Wilson went along for the run. Sean had plenty of company for his latest outdoor excursion, but last week he was solo for a shirtless adventure. Scarlett, meanwhile, flaunted her latest exercise regimen after helping Jimmy Kimmel launch Humpilates. Scarlett and Sean appear to be going strong, since they started seeing each other back in February. Many of you were happy to hear about their Spring romance despite any stigma about their age gap — Scarlett turned 26 last November while Sean is 50. Owen's found success in the relationship department, too, since his lady friend Jade Duell welcomed their son, Robert, back in January. Scarlett and Sean seem to share an interest in fitness, but he's also apparently inspiring her activism. She recently recorded a PSA for Planned Parenthood, urging women to sign a petition against a new House bill that threatens to strip the nonprofit of federal funding.

Kate Bosworth was back on the beach in Mexico this afternoon. She donned a bright yellow bikini for another day in the sun after Kate hit the sand topless yesterday. Her girls' getaway included friend and business partner, Cher Coulter, who twittered about her excitement for their trip last week. Kate will take her tan to the East Coast soon though, since she's set to attend the New Yorkers For Children Benefit Gala tomorrow night.

Kelly Preston carried her son Benjamin Travolta to a waiting car in NYC this morning. The little guy was born in November, and Kelly and John debuted his sweet face on the cover of People just a few months later. Kelly and John made the trip to the East Coast for last night's TV Land Awards, where John and the cast of Welcome Back, Kotter reunited. Kelly joined her husband for the exciting evening, and today she and Benjamin took care of other business around town while the group made an appearance on Good Morning America.

Bradley Cooper hugged a pal as they headed into lunch in LA yesterday. The newly single actor recently returned to California following his press tour for Limitless, which took him to Berlin and Spain. The movie is still holding strong at the box office even after four weeks in theaters. Bradley can now turn his attention to his next film, The Hangover sequel, which will be released next month. We've already taken a look at the hilarious The Hangover: Part 2 trailer, and we can expect to start seeing Bradley back on the promotional circuit soon, including an appearance on Late Night With Jimmy Fallon this week.

Salma Hayek was dressed up for another day of filming in Boston this afternoon. She worked on a scene for Here Comes the Boom at Logan Airport after arriving in the city with her daughter, Valentina, just last week. We haven't seen Valentina join in on the on-set fun like she did during Salma's last project, which brought the mother-daughter duo to Spain. Salma has more than movies in her future, though, since she's also introducing a beauty line inspired by her grandmother.
