Alex Rodriguez is reportedly 'upset' by Jennifer Lopez, Ben Affleck reunion

Alex Rodriguez isn't too happy with the news of  a new romance brewing between his ex Jennifer Lopez and actor Ben Affleck. Rodriguez is reportedly `upset` and `shocked` on hearing the reunion of Lopez with Affleck, sources confirmed E! News.

Friendly exes and American actors Jennifer Lopez and Ben Affleck spent last week together as the duo took a trip to Montana. After the news broke, sources near to Alex Rodriguez shared how the retired MLB player is processing his thoughts about the `unexpected` reunion.

A source close to Lopez told E! News that Alex is `flabbergasted` more than anything else, especially since they officially broke up and called off their engagement just a month ago.

"A-Rod is shocked that J.Lo has moved on. He truly thought they would be able to make it work and reconnect. He has been reaching out to J.Lo trying to meet with her and she has been very short with him," the source revealed.

According to the source, Alex is "saddened" about Lopez`s reunion with Ben, so much so that he has reached out to her to let her know "he is upset."

However, summing it up the insider told, "She is not interested in rekindling anything with A-Rod and is done".

The news of Bennifer`s reunion comes exactly a month after Lopez and Alex split after four years of being together. Days later, she and A-Rod reunited briefly in L.A. in late April and a source told the outlet that he wanted to "work things out" with her.

However, Ben was then spotted at her home in the city. At the time, another source said they were "just friends." However, the pair soon realised their chemistry cannot be denied.

This is not the first time that JLo and Affleck have paired up. Back in 2002 the two were the hottest pair in Hollywood when they began dating while filming the famous box office bomb `Gigli`. The actor proposed that November 2002 with a 6.1-carat pink solitaire custom-made Harry Winston diamond ring. However, just days before their September 2003 vows, the couple, deemed 'Bennifer' by fans, called off their Santa Barbara, California wedding. 

Months later, in January 2004, they confirmed they had officially split. In 2014, Jennifer said on the `Today` show her and Ben`s breakup was probably her "first big heartbreak." Lopez went on to marry Marc Anthony while Affleck married Jennifer Garner.
