Washington: Brad Pitt and Angelina Jolie keep their relationship strong by doing yoga together, according to sources.
The Hollywood stars have been working with Indian spiritual teacher Guru Ram Lalji to bring harmony to their five-year union.
"They`ve been practising his Siddha yoga and they start and end the day by chanting a sacred word he``s given them,” Contactmusic quoted a source as telling Now magazine.
"It`s transformed their relationship - they``ve both cut back on drinking and no longer argue," the source added.
The couple raise six children together, Maddox, nine, Pax, seven, Zahara, five, Shiloh, four, and two-year-old twins Knox and Vivienne.
