Jennifer Lopez fans have voiced their concern for her young daughter, Emme.

It comes after the "Jenny From The Block" singer's reunion with Ben Affleck.

"Bennifer" - as they are affectionately known - couldn't keep their lips off of one another during a family dinner at hotspot Nobu in Malibu on Sunday night.

The two A-listers were also joined by Lopez's 13-year-old twin children son Maximilian and daughter Emme. Together they were celebrating JLo's sister Lynda's 50th birthday.

Of the reunited couple's PDA-packed outing, a Nobu source told People on Monday: "Jen and Ben sat next to each other and were very affectionate. They held hands under the table."

"It wasn't just kissing and cuddling for the stars, as the two did spend some time bonding with her family."

But what fans couldn't help but notice was that the Selena star's daughter had chopped and dyed her brunette locks blue.

It caused social media commenters to wonder if Emme was "acting out" due to her mom moving on so quickly with Affleck.

"It was only a month ago you were KISSING Arod in front of those kids. They look so disturbed, like they've seen too much in their young age. J Lo has no shame, she is a vain, selfish, conceited, woman," a very very shady comment read.

"You can tell by Emme's hair that she is upset about the recent events," a second added.

"Why is she involving her kids so soon after she had them playing siblings with ARod's kids? Slow down," a third commented.

Alex Rodriguez dropped down to one knee and proposed to the Lopez with the impressive 15-carat emerald cut diamond ring while on holiday in the Bahamas in 2019.

In April, Jennifer and Alex were hit with break up rumors.

They came out with a statement insisting split claims were "inaccurate" and they were "working through some things."

The defiant couple subsequently packed on the PDA for cameras during a family trip when they were spotted kissing in the Dominican Republic.

But in May the couple split for good.

Jennifer's twins Emme and Max, who she shares with ex-husband Marc Anthony, grew close to Rodriguez's two daughters, Natasha, 14, and ten-year-old Ella, whom he shares with ex-wife Cynthia Rodriguez.

J-Lo's romantic history has played out in the tabloids for years.

In 2001 she received a ring from backup dancer Cris Judd worth a reported six figures. The couple were married one month later on Sept. 29, 2001 - but that marriage ended in divorce in 2003.

Jennifer received an impressive $4million eight-carat sparkler from Marc Anthony when he proposed in 2004. This was her longest marriage, lasting until 2014.
