Ben is on her mind.

Jennifer Lopez briefly mentioned her husband Ben Affleck on “Jimmy Kimmel Live!” Monday night amid the ongoing rumors that the couple’s marriage is falling apart.

The “Hustlers” actress, 54, told Kimmel about meeting Barbra Streisand early in her career, when she was initially engaged to Affleck, 51, in the early 2000s.

“She was asking me to look at my engagement ring at the time that Ben had given me years ago,” Lopez recalled of her interaction with Streisand, now 82.

Lopez said that Streisand told her, “So that’s a big diamond.’”

“And I was like, ‘Yes, it is,’ ” Lopez added.

Lopez and Affleck were initially together from 2002 to 2004. They ended their engagement in January 2004 after delaying their wedding “due to the excessive media attention” that surrounded the couple at the time.

Following the breakup, Affleck went on to marry Jennifer Garner in 2005. The couple had three children — Violet, 18, Seraphina, 15, and Samuel, 12 — before their divorce in 2018.

Lopez, for her part, married fellow musician Marc Anthony in 2004, having twins Max and Emme, 16, with him before the couple divorced in 2014.

Affleck and Lopez reunited nearly two decades after they called off their initial engagement. They married in July 2022 in Las Vegas after a three-month engagement.

They later staged a more elaborate ceremony the following month in front of friends and family.

But in the last week, the couple have been subject to split rumors.

It all started when Lopez attended the 2024 Met Gala solo on May 6. Then, it was reported that Affleck is staying at a separate house from Lopez, who was seen house hunting without her husband.

The A-listers were not spotted in public together for 47 days until May 16, when they arrived separately at an event for one of their kids in Los Angeles.

Despite stepping out several times together afterwards, Affleck was not at the LA premiere for Lopez’s new Netflix movie, “Atlas,” on Monday night.

The “Let’s Get Loud” singer arrived at the red-carpet event all on her own, but she did have her wedding ring on.

Earlier that day, Affleck was photographed shooting “The Accountant 2” in LA.

Amid the rumors about their marriage, In Touch reported that Lopez and Affleck are in therapy to work on their issues.

“Ben believes in therapy, to a point, and is willing to be a good sport about participating with an open mind, even though he hates the whole humiliating process,” a source told the outlet.

Lopez and Affleck have not publicly addressed the split rumors.
