Told ya so!
the British funnyman confirmed Wednesday the two are in fact an item.
Brand -- whose divorce from Katy Perry just became finalized this past Monday -- has been recently spotted out and about with Isabella, who's the little sister of actress Jordana Brewster, one of the stars on the new Dallas reboot. (Jordana also appeared in Fast & Furious.)
Speaking about Isabella on Howard Stern's radio show, Brand said: "Some things in the newspaper aren't true ... that's true, actually," adding that he's "just kind of enjoying the freedom" of being single.
The Arthur star indicated that someone -- probably Isabella -- was with him in bed during the radio interview with Stern.
A source tells RadarOnline.com that the duo, who met through mutual friends in recovery, has been spending a significant amount of time together over the past few weeks, but that they are keeping it casual for the time being.
Brand also opened up to Stern about his ill-fated marriage to the Firework singer, which ended in divorce after only 18 months.
"Before we got married, I just thought, 'I've got to marry her, I just love her so much.'" Brand told Stern. "And then we got married and I thought, 'Okay, this isn't really working out.'"

But, ever the gentleman, Brand insisted there's absolutely no bad blood between the former lovers.
"It was a lovely relationship ... it mostly didn't work for practical reasons ... We did work it out, she's happy, I'm happy," he added.
When asked why he walked away from his marriage to Perry without trying to score half of the $44 million she earned during their union, Brand said "I've got a good job. I'm not into taking money from women."
