The former Westlife singer, 36, announced his split from the model and TV personality a year ago (Jul15), after three years as husband and wife.
They insisted the break-up was amicable and even continued to live together and enjoy nights out for months after the separation, but now Brian admits they are no longer on speaking terms.
During an appearance on British talk show Loose Women on Monday (25Jul16), he admitted, "I'm not in contact with Vogue. Not anymore. I think before there may have been some unfinished business but we have both now moved on."
Brian has even had a wrist tattoo of their wedding anniversary covered up with a new inking of the Batman logo.
The marriage was his second, after previously tying the knot with singer Kerry Katona, the mother of his two daughters. He was also engaged to Australian model and singer Delta Goodrem.
