American billionaire, Harry Macklowe,82, who recently married his long-term mistress Patricia Landeau, appeared to take a swipe at his ex-wife of 58-years Linda Macklowe, 80.

The Real Estate Mogul who got married Patricia last week celebrated their big day by installing portraits of himself and his new wife on the side of the building at 432 Park Avenue in New York.

Mr. Macklowe told the publication he had erected the Park Avenue installation to represent his pride in his relationship and achievements, but many saw it as a dig at his ex, Linda, after their bitter divorce.

“Our smiling faces will be on a building that I built — and I am proud of my wife, my life, my friends and colleagues,” he said, adding it “gives me a great thrill” to “share this moment of joy and happiness”.

Mail reported that Linda, 80, filed for divorce in 2016, after learning that Harry had been putting Patricia, who is in her early 60s, up for at least two years in another property.
