Sam Asghari is moving forward as a newly single man ... walking his dog without his wedding ring.
Britney Spears' estranged husband was spotted in public Monday for the first time since their divorce, and he was sporting a naked ring finger.
Sam was walking around Pasadena with the Doberman Porsha, he gifted Britney back in 2021 when they were engaged.
The actor was also showing off his muscles in a sleeveless black tank top ... the day after Britney had a divorce party with a bunch of shirtless men.
Sam joked over the weekend about needing help picking a disguise to hide from the paparazzi ... but here, he's only wearing a hat and sunglasses and not shying away from the cameras.
Remember ... Sam filed for divorce from Britney last Wednesday, and as we first reported, he moved out of their mansion after he believed Britney was cheating on him with a staffer at their home.
We also saw Britney without her wedding ring on the same day Sam filed for divorce, taking it off before tooling around in her Mercedes.
Now, Sam's shed his ring too.
