The couple split in May last year (11) after Schwarzenegger confessed to fathering a lovechild with a maid at the family home over a decade ago, and Shriver filed papers to end their 25-year marriage two months later (Jul11).
They have reunited for a number of family events in the months since, and reports suggest the longtime partners have enrolled in couple's therapy as they attempt to patch up their strained relationship.
The Terminator star has now dismissed the gossip, although he insists he and Shriver will always be a team when it comes to raising their four kids.
He tells U.S. news show Extra, "We work together even though we're going through a divorce. Luckily, Maria has been a terrific mother."
