Mayor Eric Adams said Tuesday he hasn’t spoken to President Biden in months — further exposing the apparent widening rift between the pair as the Big Apple and nation reel from the migrant crisis.

“I haven’t communicated with him [Biden] since earlier this year,” Adams — who has become increasingly vocal against the president’s handling of the border — said on WABC-TV’s “Eyewitness News.”

The Dem mayor said he only spoke on Monday with a member of Biden’s Democratic administration — the president’s chief of staff, Jeff Zients, whom New York Gov. Kathy Hochul was shoved off on during her trip to Washington, DC, last month.

Adams told CNN last month he hadn’t directly spoken with the president since 2022 — so the dry spell in personal relations between the once-buddy-buddy pair could be even longer.

The mayor has recently ratchetedup his attacks on Biden while demanding the feds provide more funding, work visas and shelter sites so the city can better grapple with the tens of thousands of asylum seekers flooding the Big Apple.

Hizzoner’s seething rhetoric is a drastic change from when Biden visited New York in 2022 — and Adams dubbed himself the “Biden of Brooklyn” and the president’s favorite mayor.

Since then, the city has received an estimated 110,000 new migrants, and nearly 60,000 of them are in its overloaded shelter system.

The price tag for the Big Apple to handle the flood of migrants is expected to reach $12 billion by 2025 — and help result in up to 15% cuts in city agency spending by next spring.

The feds have only allocated just under $150 million for New York City to deal with migrants.

The apparent ever-growing divide between Adams and the Biden administration was also on full display at Monday’s 9/11 remembrance services — with Hizzoner frostily grimacing as Vice President Kamala Harris stood next to him chatting with Hochul.

Adams told The Post he only made small talk with the vice president and did not bring up the migrant crisis.
