That was quick!

Rep. Ilhan Omar’s ex-husband has remarried — just 37 days after their divorce was finalized, according to a report Monday.

Ahmed Hirsi, the father of Omar’s three children, tied the knot to nurse Ladan Ahmed in a low-key ceremony in Somalia in a bid to avoid media scrutiny, the Daily Mail reported.

Hirsi (D-Minnesota), 39, married Ahmed on Dec. 12 in a Muslim ceremony. The pair are now in Saudi Arabia on their honeymoon, according to the report.

Omar and her husband filed for divorce this past October amid allegations she was having an affair with DC political consultant Tim Mynett.

Omar and Hirsi officially became single on Nov. 5 and Hirsi, the Mail reported, married his new bride just 37 days later.

In a photo shared on Instagram on Jan. 2, Hirsi is smiling next to a woman believed to be his new bride in Mecca, Saudi Arabia, Islam’s holiest city.

“I look forward to this new chapter in my life and I ask you all to join me in celebration,” he captioned the photo.

The post has dozens of comments from friends wishing the pair congratulations and blessings for their marriage.

Omar’s own alleged lover was seen grinning from ear-to-ear as he walked out of a Washington, DC, divorce court on Dec. 19 after officially splitting from his wife.

In August, The Post first reported the bombshell allegations that Omar was having an affair with Mynett, who had been on her campaign’s payroll.

Dr. Beth Mynett, now Dr. Beth Jordan, claimed her husband confessed in April that he was having an affair with the Somali-born congresswoman before he ditched her, according to the divorce documents.

The pair denied the allegations and Omar insisted in an Aug. 28 interview that she and Hirsi were not separated and seeing other people.

But one friend of the couple told The Post that Omar and Hirsi separated in March, and claimed Omar repeatedly asked her husband to file divorce papers.

Hirsi refused, the friend said, and told Omar if she wanted a divorce she should file for it herself.

Omar and Hirsi had their own complicated marital history, first becoming engaged in 2002 and marrying in a faith-based ceremony before splitting in 2008.

The next year, the congresswoman married another man, before splitting with him in 2011 and getting back with Hirsi and having their third child in 2012.

Omar and Hirsi legally wed before she was elected to the US House of Representatives in 2016, but the marriage would end in divorce the next year.
