Willis, 24, threw on a flannel shirt over her workout clothes and kept her hair swept up in a messy top knot, hiding her eyes behind a pair of oversized shades. Her 50-year-old mom Moore, meanwhile, donned a black beanie, loose cardigan and scarf for her post-workout outfit.
The mother-daughter duo wore matching grey flats.
The pair was first spotted leaving the yoga studio together just last month after many months of estrangement. Willis' boyfriend Jayson Blair was also in tow for the healthy outing.
In July 2012, rumors circulated that Willis and her sisters Scout, 21, and Tallulah, 19, were trying to file a restraining order against Moore after the Ghost actress had allegedly been calling and emailing them incessantly.
"It's true they're not all hunky dory, getting along like they used to, but they're not about to go to those extremes!" and insider told Us of the situation. "They love their mom at the end of the day, and they're never going to completely abandon her." (Moore shares the girls with second ex-husband Bruce Willis.)
Moore split with husband Ashton Kutcher back in November 2011 and did a stint in rehab in February 2012 following a headline-making meltdown. Kutcher, 35, reportedly cheated on his wife at the San Diego Hard Rock Hotel on the couple's sixth wedding anniversary after a flirty encounter with a woman named Sara Leal turned sexual.
Since their split, Kutcher has been dating former That 70s Show costar Mila Kunis, and the pair most recently had a double-date with Princess Beatrice and her American boyfriend Dave Clark in London on Saturday, May 11.
