Mark Ruffalo

Gwyneth Paltrow hopped on a bike to film Thanks For Sharing in NYC this afternoon. She changed into a black Stand Up 2 Cancer shirt for another scene with costar Mark Ruffalo after the duo started working together on set this week. Gwyneth made the trip to the East Coast from the UK on Sunday, and she was spotted at the airport with pal Cameron Diaz. The stylish girlfriends partied at The Arts Club and celebrated pal Stella McCartney's birthday during their time in London. Gwyneth may be back to work, but it looks like she's having a great time on set since she tweeted "Shooting in sunny central park. Reminds me of my youth." and was also spotted sharing a laugh with Mark. He's a little more serious in the new trailer for The Avengers, which gives fans a quick glimpse of him in character as The Hulk.

Gwyneth Paltrow threw on a pair of spandex pants today to film Thanks For Sharing in NYC's Central Park with her costar Mark Ruffalo. The pair shot a scene for the raunchy comedy in which Gwyneth causes a stir with some potentially awkward stretching in front of Mark, who's playing a sex addict. It seems she was on set yesterday too, as someone on Twitter joked about seeing Gwyneth's trailer in front of their apartment when they woke up. Gwyneth, in a joking mood, wrote back, "That's my regular car! Thanks for letting us shoot on your street. I heart Brooklyn." Gwyneth's in the Big Apple to get down to business with Mark after traveling from the UK on Sunday with her pal Cameron Diaz, who was out in the city recently too visiting her gym. It's time for Gwyneth to get back to work following a fun few weeks in the UK that saw her celebrate Stella McCartney's birthday two times, as well as perform before the Queen's husband Prince Philip. She spent time in the UK with her kids, Moses and Apple, while husband Chris Martin was off on tour with his band Coldplay. Chris and the group have a show in Spain later this month, then will be in the UK for a string of dates later this Fall.

Miranda Kerr stepped out for lunch Saturday at LA's Cheebo with her son Flynn. She's home again in California following a quick trip last week to South Korea, where she did interviews and had a few changes including a traditional South Korean costume, for photo ops on behalf of one of her many contracts. Miranda changed into an orange dress by the evening to attend a Global Green party at the Fairmont Miramar Hotel with her husband Orlando Bloom. They mingled with his Sympathy For Delicious director and costar Mark Ruffalo at the bash, which also brought out box office winner X-Men: First Class star Kevin Bacon and his wife Kyra Sedgwick. Orlando is a longtime celeb supporter of the eco organization, since both he and Miranda are well known for their advocacy on behalf of green causes.

Miranda Kerr rocked a sheer black tank top while out running errands in NYC yesterday. She and husband Orlando Bloom were in the Big Apple for the past week with their young son Flynn. Orlando has been busy during the annual Tribeca Film Festival, first debuting his medical drama The Good Doctor and then having a small party to celebrate the Mark Ruffalo-directed Sympathy For Delicious. Orlando and Mark apparently headed back west recently, though, as they were together in LA for yet another screening of their movie at the West Hollywood Mondrian Hotel.

Orlando Bloom joined Sympathy For Delicious costars Mark Ruffalo, Christopher Thornton, and Laura Linney last night at a screening of the film. It was over a year ago Sympathy For Delicious made its first debut at the 2010 Sundance Film Festival and last month Mark, who also directed the piece, released a new trailer. Christopher wrote the story and plays the lead character in the unique story about a DJ who finds himself with the ability to heal people through faith. Orlando has the role of another band member in the movie, which gives fans the opportunity to see him decked out in rock star leather pants and muscle tees. This is the second screening for Orlando in a week, having already walked the red carpet over the weekend at the Tribeca Film Festival with his "hot" wife, bikini model Miranda Kerr, in support of The Good Doctor.

The 2011 Oscars have come and gone, but we're still basking in the glow from the red carpet. It was so fun to bring the action to you live here on PopSugar, and a big thanks to everyone who watched! Last year we spotted George Clooney's flask and Kristen Stewart's hug with her dad, and this time it was everything from Nicole Kidman warming up Gwyneth Paltrow to everyone's excitement over seeing Sandra Bullock return to the Academy Awards. We're still bringing you all the best pictures from all the events and afterparties, so enjoy our most memorable moments!
