‘Bachelorette’ Charity Lawson’s master’s degree helped her navigate dating 25 men

She got into their heads first — and then their hearts.

Bachelorette Charity Lawson has her master’s degree in clinical mental health counseling — which she said gave her a leg up when it came to dating 25 men at one time.

“It definitely helps me navigate … those important conversations, but also looking for those behaviors that may show up either as green flags or red flags,” the Georgia native told The Post.

When the leading lady — who searched for a soulmate on Season 20 of the ABC dating series, which premieres on Monday — was asked by producers what she was looking for in a partner, she described a man with a work ethic that matched her own.

“I definitely said career … ambition,” Lawson, 27, said.

She got what she wished for because there were a bunch of brainy men vying for her heart — with professions such as biomedical scientist, physician, attorney, and data scientist, and another getting his graduate degree from Harvard.

“Yeah, all great careers, incredibly successful, which is great,” she said. So … that stability piece.”

The Auburn University graduate was a contestant on the last season of “The Bachelor” and was in the leading man Zach Shallcross‘ final four, but then was eliminated the following week.

Before she joined the franchise, she had 1,200 Instagram followers — but after her television debut, she watched her amount of fans drastically increase.

“Number-wise, it’s insane. Middle of Zach’s season, I was maybe at like 30K, and once I was announced as the Bachelorette it just continued to increase,” said Lawson, who now has 110,000 followers on the platform.

Another thing that surprised the reality star was the amount of heat the Bachelor Mansion generated — and it wasn’t just from the hot make-out sessions.

“There are so many fireplaces,” she said. “And I’m like, ‘Why are there so many?’ Like more than you can probably imagine.”
