The actor was seen wearing a sports cap emblazoned with the letter 'B' as he took girlfriend Bianca Wallace's dog, Bear, out for a walk in Los Angeles.
He cut a casual figure as he donned cream-coloured trousers, a navy long-sleeved top and a navy puffer jacket.
His outing comes after it was revealed that the actor filed a restraining order against Alice and submitted 113 pages of messages and social media posts as evidence.
She has denied his claims.
The 48-year-old is now dating actress Bianca, 28, and claims that his ex-wife has been harassing her too.
Ioan has requested that Alice is to stay 100 yards away from himself and his new girlfriend Bianca and that she should not be able to contact them.
In response, Alice has denied all of his claims and has said that she does not agree to a no-contact order or a stay-away order.
She says in the court documents: "I believe that Petitioner is filing this request merely as a ploy to gain some sort of advantage over me in our court proceedings.
"As Petitioner has not seen our children for over 8 months, I believe he is trying to set some sort of record that I am a horrible mother.

"As such, I ask the Court to deny Petitioner's requests. Ever since I received Petitioner's Ex Parte notice informing me that he will attempt to seek a domestic violence restraining order against me, I have been besides myself terrified that he will stop at nothing to hurt me emotionally and financially, and more alarming, try to take our children away from me.
"I have cried on and off all day terrified over what his lies have done to our family, and what they continue to do. I suspect Petitioner will not be truthful in his declaration and make things up to make me sound like an abuser, as this appears to be his strategy from day one."
Alice has previously been outspoken about how she has been handling the divorce and the news of his new girlfriend.
She has taken to social media to put both Bianca and Ioan on blast and even made TV appearances explaining her side of the story.
Welsh actor and Hollywood star Ioan and soon-to-be ex-wife Alice were married in 2007 and share two daughters together.
