Ashton Kutcher and Demi Moore were first spotted together for the first time since their bitter separation two years ago. The exes were caught on camera leaving Burbank Airport on Monday, September 9 after getting off of the same flight in Los Angeles.

Kutcher, in casual jeans and cardigan on top of his button-down, was seen talking cordially and privately to his estranged wife, who stayed quiet, while they were leaving the terminal. They parted ways when reaching the parking structure of the airport. "Bye Demi!" he said.

The "Margin Call" actress was accompanied by a female friend. The 50-year-old star donned a sweater over her beige dress and leggings and carried a big tote bag. She reportedly ran into her estranged husband when attending a tech conference in San Jose.

Kutcher, 35, split from Moore in 2011 after six years of marriage following his alleged cheating scandal. He filed for divorce in December 2012 and she responded with her own papers in March this year. She's seeking spousal support and attorney fees from the actor.

Despite their split, the couple continues their joint charity work, Thorn. Started by Demi and Ashton (DNA) Foundation in 2009, it is to defend children against online predators. "Thank you to everyone one on the @thorn tech task force. Your dedication and pursuit of a better world will echo for generations," Kutcher said on Tuesday.

Kutcher has dated his former "That '70s Show" co-star Mila Kunis, 30, for around a year now. While he was in California, his girlfriend was in Canada to promote her new movies "Blood Ties" and "Third Person" at the Toronto International Film Festival.

The couple recently sparked engagement rumor after Kunis was spotted wearing a band on her left ring finger.
