Anna Wintour and telecom tycoon Shelby Bryan are no more -- and have been for quite some time, according to reports on Thursday.

While the reason for the breakup remains unclear, Page Six reported that the pair had begun seeing cracks in the foundation in 2013 after it was reported Bryan was allegedly on the hook to the IRS for some $1.2 million in back taxes.

Per People magazine, citing a source on Thursday, the couple privately split years ago, and an insider relayed a similar sentiment to Page Six in 2013, telling the outlet, “It’s been quite a while since they’ve been seen together."

However, according to Page Six, citing sources, that is not the case. “Katherine and Shelby have kids together [and] are friends. That’s all," insiders said. 

The Vogue editor-in-chief, 70, and Bryan, 74, first met back in 1997, according to a New York magazine profile on the Vogue head honcho. They tied the knot in 2004.
