Charlie Sheen reunites with ex-wife Denise Richards to watch their daughter Sam ride horses in Malibu amidst rumours he's moving to Mexico

They have been embroiled in a legal battle.

But on Tuesday it appeared Charlie Sheen and ex wife Denise Richards put their squabbles aside to spend the day with their daughter Sam at a horseback riding class in Malibu.

The 50-year-old Anger Management actor kept things very casual for the outing, opting for a grey long sleeve shirt over a similar white shirt, khaki cargo shorts and black trainers.

He also donned a black beanie and some rectangular shades. 

As daughter Sam, 12, trotted by, the Platoon star decided to take several snaps of his budding equestrian with his phone.

Ex-wife Denise, 45, was also present at the facility, and decided to take her dog for a walk while Sam was out riding.

The World is Not Enough actress looked ready to work out in a black tank top, black cropped Lycra leggings and bright pink trainers. She tied a matching pink track suit top around her waist.

Meanwhile, Charlie is reportedly planning to leave America and retreat to a quiet retirement community in Mexico.

He has reportedly purchased a home in the sleepy town of Rosarito in Baja California, Mexico.

His real estate agent Scott Weier told Dailymail.com: 'It's just a humble little three-bedroom house, around 2,700 square feet. It wasn't too expensive.'

'He told me he's planning on living here full time, he's tired of the rat race of the United States and his life the way it is. He wants to do something a bit different. He's looking for a change. Compared to what he has in Los Angeles it's very humble and simple.

'He's certainly not coming here to impress anyone with a huge mansion on the ocean.'
