The celebs were both in attendance at the VAX Live Concert on May 2, though they arrived separately. Though ever since, it seems Lopez and Affleck have been inseparable, as a source has confirmed to E! News.
Following the concert, the pair jetted off to Montana, where they spent a week at Yellowstone Club.
Lopez and Affleck had previously been engaged for a period of two years, though broke up in 2004. Everyone is shocked to see the couple back together - especially as Lopez recently ended another engagement.
The singer parted ways with ex-fiancé Alex Rodriguez last month, after being together for four years. The two apparently agreed that they were "better as friends."
Much has changed for both Lopez in Affleck in the 17 years since their split. They both got married, became parents and went through divorces in their time apart, and now it seems they are both in a similar place in life again.
Lopez was married to singer-songwriter Marc Antony from 2004 to 2014. She shares her two children with him. Similarly, Affleck shares three kids with ex-wife Jennifer Garner, to whom he was married from 2005 to 2018.
Like Lopez, Affleck is also recently out of a relationship. He had been dating actress Ana de Arma since early 2020, and broke up earlier this year.
Even with everything that has changed for each Lopez and Affleck in the past 17 years, the two have always remained connected.
"They have been in touch here and there throughout the years," another source reported to E! News.
"Ben reached out to her to see how she was doing and they had dinner together a few times within this last month. It's natural between them and the chemistry is unreal. They picked up where they last left off and are enjoying each other's company right now."
