Reese Witherspoon Jokes About Stealing Sofia Vergara's Earrings at Stand Up to Cancer Event

The pair, who bonded earlier this year while shooting an action comedy about a police officer who goes on the run with the glam wife of a drug dealer (you can guess which is which), caught up backstage at the Stand Up to Cancer event in Los Angeles on Friday.
Witherspoon, 38, appeared to have taken a page out of the Modern Family star's style book with her bold red lips and diamond hoops.
"Sorry I stole your earrings @sofiavergara and please #SU2C," she captioned an Instagram pic of her and her "work wife" along with Vergara's boyfriend, True Blood star Joe Manganiello.
Vergara also shared her love for her celebrity bestie, posting a photo on Instagram along with the line, "Reunited with the most beautiful girl in the world!!!"
Stars including Jennifer Aniston, Jon Hamm, Pierce Brosnan, Rob Lowe and Katie Couric wore their Stand Up to Cancer tees at the annual telethon, which raises funds for cancer research.
Vergara, 42, told PEOPLE that the event was "very special" to her because she beat thyroid cancer in her late 20s.
She wore a T-shirt at the event that said "Survivor."
"They sent me my T-shirt and mine is different than the others," she said. "I kind of don't like it, but it is what it is and I'm so happy to be free of cancer and I can come here now and support."
