They attended the VAX Live concert together in L.A. on Sunday before reportedly heading away together for a week-long break in Montana. Sources say it was "just the two of them".
Jennifer and Alex Rodriguez called off their engagement last month after 4 years together and Ben split with his girlfriend Ana de Armas in January.
They first started dating in 2002 and were engaged within the year but ended up calling off their 2003 wedding just days before they were due to get married. "Bennifer" stayed together until January 2004.
By October 2004, Ben was dating Jennifer Garner after meeting on the movie "Pearl Harbour" in 2000. They got engaged in 2005.
Everyone was shocked when Ben and Jennifer Garner announced their split in June 2015 after 10 years of marriage. He started dating producer Lindsay Shookus in 2017 but they split within a year as he was "never fully committed" to her.
His divorce from Jennifer Garner was finalized in October 2018.
