Jon Hamm, who has an estimated net worth of $30 million, is back on the market again. His being single came after he and his longtime girlfriend, Jennifer Westfeldt, decided to end their relationship after 18 years of being together.

With his remarkable talent and net worth, Jon Hamm is probably one of the richest and most handsome men on television. Known for his role as the troubled advertising genius Don Draper in the AMC's hit show "Mad Men," Hamm is definitely popular among women viewers of the show.

For the past 18 years, 44-year-old "Mad Men" heartthrob Jon Hamm has been committed to 45-year-old Jennifer Westfeldt. According to People, the ex-couple has been one of the most stable relationships in the entertainment industry. And while they openly spoke about their unique relationship, their mutual reluctance to marry seemed to have made an impact on their romance.

"We may not have a piece of paper that says we're husband and wife, but after 10 years, Jennifer is more than just a girlfriend," Hamm said. "What we have is much deeper and we both know that. To me, people [should] get married when they're ready to have kids, which I'm not ruling out."

Jon Hamm, whose net worth is $30 million as listed by Celebrity Net Worth, also said that he's not worrying about not getting married.

"I don't have the marriage chip, and neither of us have the greatest examples of marriage in our families," he added. "But Jen is the love of my life, and we've already been together four times longer than my parents were married."

Unfortunately, Jon Hamm and Jennifer Westfeldt broke up and confirmed the sad news on Monday. The breakup came following Hamm's rehab stint completion for alcohol addiction in March.

"With great sadness, we have decided to separate, after 18 years of love and shared history," the former couple said in a statement, as per E! News. "We will continue to be supportive of each other in every way possible moving forward."

Back in April, Jon Hamm and Jennifer Westfeldt denied the breakup rumors. But now, an insider close to Westfeldt told Us Weekly that the ex-couple have been in conflict.

"They've been fighting for a while, but now they're done," a source said. "They decided to finally split. It's sad."

Earlier this year, Jon Hamm's net worth has been under scrutiny and even made headlines when the "Minions" voice actor completed a 30-day rehab program for alcohol addiction. At that time, TMZ reported Hamm's rehab stint was accomplished just days before the premiere of the last season of "Mad Men."

So, will the recent breakup affect Jon Hamm's net worth?
