Ashton Kutcher and Mila Kunis were recently spotted hugging in Beijing before they climbed the Great Wall of China.

Kunis sported a navy cardigan, black shorts and white tennis shoes for the adventure. Kutcher wore a Chicago Bears cap, cargo shorts and orange running shoes. They were spotted embracing in the rain and both stars had smiles on their faces.

The trip comes at a time when both stars are quite busy in their careers. Kutcher is promoting his film Jobs, a biopic about former Apple CEO Steve Jobs, while Kunis is still in Chicago shooting her 2014 film Jupiter Ascending with Channing Tatum, Sean Bean and Eddie Redmayne.

Sources close to the pair have said that they have talked about marriage as well as having children. In a June interview with Italian magazine Io Donna, Kunis refused to answer questions specifically about Kutcher, though she did say, "But I can tell you, love is great. Love is wonderful and it's all around us [winks]... See? I just gave you an awesome quote!''

In February, Kunis was on The Ellen DeGeneres Show and when the talk show host about her about her Valentine's Day plans or made any reference to Kutcher, Kunis blushed and tried to avoid answering the questions. DeGeneres then asked if she still talks to her That 70's Show castmates, and flashed a huge image Kutcher on the big screen behind them.

"When's the last time you talked to him?" the comedian asked, referring to Kutcher, to which Kunis replied, "It's been give or take a couple of minutes."

Kunis has never been married while Kutcher separated from Demi Moore in 2011. They met on the set of That '70s Show, which aired from 1998-2006, but the stars did not start dating until Kutcher's marriage to Moore was over.
