Bruce looked relaxed as he exercised, donning a pair of trainers and striped blue socks to ensure he was comfortable.

He also made sure to stay safe by wearing a helmet and kept hydrated by taking a bottle of water with him for the cycle.

Although his wife Emma, 41, and their two daughters Mabel, eight, and Evelyn, six, were seen in California in May, this is the first time that Bruce has been seen back in the state.

In Instagram Story posts, the English/American actress showed the girls hanging out near the Santa Monica Pier.

Emma made it clear she was ready to be on the West Coast, backing the clips with the Beach Boy’s classic California Girls.

‘And then back to reality,’ she captioned one post of the stunning horizon.

Bruce was reportedly visiting his ex and adult daughters when he got stuck at Demi’s Sun Valley, Idaho residence after lockdowns swept across the states, halting travel.

Family time: Bruce previously spent quarantine in Sun Valley, Idaho with his ex Demi Moore, 57, and three eldest daughters Rumer, 31, Scout, 29, and Tallulah, 26. Emma and their girls Mabel, eight, and Evelyn, six, managed to join later

During that time Emma stayed with their daughters Mabel and Evelyn but eventually they were able to fly to Idaho to join Bruce in May.

Sources made it clear that there was nothing strange about the arrangement, as Emma and Demi have a close relationship.

‘Demi and Emma are close, and all three get on great as a big blended family,’ insider told People.’ There are no issues at all. Emma needed to stay in L.A. with the young kids.’

Emma and the girls eventually made it to Idaho, meaning the entire extended family got to spend some time in lockdown together.

Bruce and Demi were married from 1987 to 2000 and share daughters Rumer, 31, Scout, 29, and Tallulah, 26. After their divorce, he went on to marry Emma in 2009.

And Demi recently gave a glimpse into her and ex Bruce’s relationship, crediting him for her bathroom’s quirky interior designs.

The actress, 57, was asked about the plush bathroom in her Idaho home during a remote appearance on Late Night With Seth Meyers.

Seth, 46, brought it up after Demi shared a snap of her bathroom on social media, with the floor covered in brown carpeting.

Blaming her ex-husband for the decision to line her bathroom with carpet, Demi joked to Seth: ‘That originally was a Bruce Willis choice, not to put it all on him.’

Interesting choice: Demi shared a photo of herself in the carpeted bathroom that was serving as an office for her podcast Dirty Diana, and joked that Bruce was behind the design choice.
