Brian Austin Green ran errands in Los Angeles, California, dressed in his favorite Rolling Stones face mask along with a black Pink Floyd t-shirt on Monday.
The Beverly Hills, 90210 star, 47, wore his puffy blue jacket, along with green camouflage sweatpants.
It seemed to be a favorite look for the star, who sported a very similar outfit just days before.

He slipped his feet sans socks into black and white checkered Vans.
The father-of-three shouldered a black backpack and carried a paper shopping bag in one hand and a white package in the other.
Green was the third celebrity to be unmasked this season on The Masked Singer, as the Giraffe.
In addition to his acting pursuits, Brian has previously been a rapper.

In 1996 he came out with his debut and so far only studio album, a hiphop record called One Stop Carnival.
He played the drums on Esthero’s 2005 album Wikked Lil’ Grrrls, and took part in the soundtrack for the comedy drama series Wedding Band in which he starred in 2012-13.
Monday’s sighting comes as Brian remains embroiled in a feud with his estranged wife, Megan Fox.

The couple separated late last year into this spring, 10 years after getting married and having three boys together.
At the start of this month, Fox, 34, lashed out at her estranged husband for putting one of their children in a Halloween photo on his Instagram.
The Transformers star questioned why their youngest son Journey, four, was not cropped out of the shot and claimed it was a tactic to highlight Brian as the better parent.

Commenting on the post, she wrote: ‘I had a great Halloween with them yesterday, and yet notice how absent they are from my social media.
‘I know you love your kids, but I don’t know why you can’t stop using them to posture via Instagram.
‘You’re so intoxicated with feeding the pervasive narrative that I’m an absent mother, and you are the perennial, eternally dedicated dad of the year. You have them half of the time.’

She added: ‘Congratulations you truly are a remarkable human! Why do you need the internet to echo back to you what should be inexhaustibly evident in the way your children love you?’
Brain took down the original photo before uploading a new one, with Journey cropped out.
And as seen last week, the estranged couple are far from dealing amicably with their separation, as Megan has reportedly become ‘unpredictable’ towards her husband.
‘Megan and Brian have taken a turn for the worse because Megan can be unpredictable and inconsistent, which is a big reason that they separated in the first place,’ a source told Us Weekly.
