Maria Shriver and Arnold Schwarzenegger spent Christmas together at their Brentwood, California home with their children, according to a report.
It comes as the journalist, who filed for divorce from her husband in June, is said to be 'reconsidering ' their divorce.
People cite a source close to the family who reveals that the couple 'had a really nice time' over the holiday.
According to the source, they also attended the Los Angeles Lakers' season opener game at the Staples Center in the afternoon.
The pair have spent been spotted with each other frequently since the announcement of their split in the wake of it being revealed that Arnold fathered a love child.
Shriver, 56, was by her ex's side on his 64th birthday in July.
The former couple, married 25 years before announcing their separation in May, have four children together: Katherine, Christina, Patrick and Christopher.
Shriver filed for divorce from her husband after he admitted earlier this year to fathering a love child with their former maid Mildred Baena 14 years ago.
But it appears that Maria Shriver is reconsidering the move.
Due to a number of factors, including her Catholic beliefs, she has reportedly told friends that she is having second thoughts, sources have told TMZ.
Most devout Catholics do not believe in divorce.
The decision for Shriver is said to have been made even more difficult with Arnold's attempts to woo her back.
The Terminator star, 64, has apparently been showering her with gifts and acting 'extremely sweet' towards his estranged wife, according to the website.
Since announcing their split, the couple have been remaining amicable for the sake of their children.
They were even seen attending church together last month.
Maria is also still visiting Arnold's favourite Beverly Hills salon Guiseppe Franco.
She had her hair perfectly coiffed there earlier this month.
The Terminator star also organised haircuts for himself and sons Patrick, 18, and Christopher, 14, the same week.
The Schwarzenegger family shearings is perhaps one sign that Arnold and Maria are amicably working through their difficulties.
The pair split in May - following 25 years of marriage - when the former California governor and action movie star confessed he had fathered a young boy named Joseph with Baena.
The couple are also parents to two daughters: 21-year-old Catherine and Christina, 20.
