Former President Joe Biden’s daughter, Ashley Biden, publicly accused her husband, Dr. Howard Krein, of having a girlfriend just before she filed for divorce.

Early Sunday, the day before she submitted her petition to dissolve her 13-year marriage, Ashley took to her Instagram Story to upload a photo taken from behind a couple that was holding hands while walking down a sidewalk.

“My husband and his girlfriend holding hands ❤️,” she wrote atop the image, which she set to the tune of Notorious B.I.G. and Lil’ Kim’s “Another,” a song about infidelity.

While the former first daughter’s message was clear, Krein was not immediately identifiable by the picture.

The dark-haired man was seen wearing a white polo shirt with dark pants and sneakers, while the dirty-blond woman donned a black strapless dress.

Ashley, 44, quickly deleted the post, and reps for Krein, 59, did not immediately respond to Page Six’s request for comment.

Ashley, whose mother is former first lady Jill Biden, filed to end her marriage with Krein, an otorhinolaryngologist, in a Philadelphia court on Monday.

Shortly after, the social worker appeared to celebrate the news via her Instagram Story by sharing a snap of herself walking through a park while flashing a thumbs-up.

Beyoncé’s “Freedom” played in the background.

She also reposted a cryptic quote that read, “New life, new beginnings means new boundaries. New ways of being that won’t look or sound like they did before.”

Lauryn Hill’s “Freedom Time” accompanied the post.

Ashley and Krein got married in June 2012.

Joe, 82, shared sons Beau, 56, and Hunter, 55, with his first wife, Neilia Biden, who died in a car crash in 1972 along with their 1-year-old daughter, Naomi.
