Chris Hemsworth

Chris, Liam, and Luke Hemsworth joined several celebrities in LA on Saturday for City Year's third annual Spring Break: Destination Education party, a fundraiser to keep at-risk students on the path to graduation. The Hemsworth brothers posed on the red carpet with AmeriCorps members — who serve as tutors, mentors, and role models to students — while television heartthrobs Ed Westwick and Max Greenfield followed suit. The nonprofit cause also brought out Julianne Hough, Rashida Jones, Hailee Steinfeld in a striped Dolce & Gabbana dress, Octavia Spencer, and others.

Inside the event, stars snacked on food, checked out interactive booths, and caught performances from DJ Sky Blu of LMFAO and Skylar Grey. Octavia was on hand to pass out City Year jackets as one of the organization's host committee members, which included Channing Tatum, Anne Hathaway, Vince Vaughn, and others who were unable to attend.

Ben Affleck and his brother, Casey Affleck, were seen boarding a private jet with Ben's wife, Jennifer Garner, and their pal Don Cheadle yesterday as they left St. Lucia. On a later plane, Chris Hemsworth and his wife, Elsa Pataky, caught a flight from the Caribbean along with Jimmy Kimmel and his fiancé, Molly McNearney. The celebs were on the tropical island to watch as Matt and Luciana Damon renewed their wedding vows.

According to reports, the Damons rented out the entire Sugar Beach resort to celebrate their marriage after nearly eight years of wedded bliss. Their four daughters, Gia, Isabella, Alexia, and Stella, were there to witness the happy occasion. Matt and Luciana married in a small Manhattan ceremony in December 2005, and their weekend party gave them the chance to have the big blowout wedding they didn't do the first time around. For their vow renewal ceremony, which was officiated by Jimmy Kimmel, Matt wore a light suit and Luciana had a special gown from Naeem Khan, a friend of their family. The Damons and their guests wrapped things up with a cocktail party on a tiki-torch-lined beach.

Chris Hemsworth and his Naeem Khan-clad wife, Elsa Pataky, hit the blue carpet at last night's Oceana Ball in NYC. The pair were also joined by Chris's older brother, Luke Hemsworth, as well as Kate Walsh and Adrian Grenier for the foundation's inaugural ball, which serves to protect and restore the ocean. Although Chris and Elsa were without the company of their daughter, India, in NYC, she was far from forgotten. We were on hand at the event where Elsa gushed to the press about being a first-time parent, but also shared that she was surprised to learn how hard it is because she and Chris are "doing everything on their own."

Ahead of his big night out, Chris was able to spend some quality time bonding with his brother in the city. The brothers paired up with Elsa and Luke's girlfriend for a morning NYC stroll. Chris is perhaps making the most of his time with his brother in the States before Luke heads back to their native Australia to take on a big-screen role in the film The Reckoning Down Under.

Chris Hemsworth and Elsa Pataky took a stroll in NYC with friends and family today. The couple showed PDA while walking through lower Manhattan with Chris's brother Luke Hemsworth and his girlfriend. Chris and Elsa headed to the East Coast over the weekend after enjoying a sweet lunch date with their baby daughter, India. They are in town to attend tonight's Oceana Ball, a fundraising event that raises money to protect and restore the world's oceans, and we'll be on the red carpet tonight to talk to the stars about their commitment to the cause.

In addition to his charitable pursuits, Chris also has an upcoming project to keep him busy. The trailer for his latest film Rush was released today, and shows the Thor actor sporting a '70s-cool look while portraying British race car driver James Hunt.

Chris Hemsworth showered his daughter, India, with kisses yesterday while leaving lunch at LA's Taverna Tony with his wife, Elsa Pataky, and Elsa's mother, Cristina. He has been spending lots of time with his family lately, especially doting on his almost-1-year-old tot. Earlier this week, Chris held India close for a shopping trip at Whole Foods with Elsa in Santa Monica, and he also snuck in sweet time with his little girl during a breakfast stop the week before.

While Chris is getting in quality time with his girls, he will be losing the company of another family member at home in LA. Chris's older brother, Luke Hemsworth, who moved to LA to join Chris and their other brother, Liam Hemsworth, on the West Coast, will be heading back to the Hemsworths' native Australia to follow in his siblings' footsteps on the big screen. Luke was cast in the upcoming Aussie film The Reckoning, which will start filming this month.
