Kelsea Ballerini allegedly cheated on Morgan Evans with Drew Taggart

Talk about being “Blindsided.”

While Kelsea Ballerini and Morgan Evans’ divorce has resulted in a “he said, she said,” Page Six can exclusively reveal what allegedly happened before the former couple’s marriage fell apart.

An insider claims to us that the country-pop songstress cheated on her now-ex-husband with The Chainsmokers member Drew Taggart in August 2019 at Lollapalooza — after having collaborated on their hit 2018 track, “This Feeling” — but didn’t come clean about it to Evans until 2021.

We’re told the alleged affair, combined with other issues, led to Ballerini, 29, calling it quits with Evans, 37, last summer and “blindsiding” him with her decision.

A source close to Taggart, who recently has been linked to Selena Gomez, tells Page Six that the DJ, 33, was single at the time of his rendezvous with Ballerini.

Ballerini filed for divorce from Evans last August after nearly five years of marriage. Court documents obtained by Page Six at the time showed that she cited “irreconcilable differences” as the cause of their split.

Shortly before the “Just Married” singer’s interview on “Call Her Daddy” dropped late Tuesday, Evans took to Instagram to call out his ex-wife for not sharing the “reality” of their divorce, which was finalized in November.

“It’s really sad for me to see this person, who I spent so much of my life with, and loved with all my heart, saying things that aren’t reality and that leave out what really happened,” he wrote.

“She knows I’m not the type of guy to speak on those things publicly. If this is what she needs to heal, I hope it helps. All I ask is that if you’re on my pages, please don’t be mean. Don’t be mean to Kelsea, don’t be mean to each other.” – Source
