Jennifer Lopez Photographed Wearing What Looks Like Ben Affleck's Flannel Shirt: Report

Jennifer Lopez stepped out Thursday in what appears to be a shirt that belongs to her on-again boyfriend Ben Affleck.

Lopez, 51, was photographed stepping off a plane in Los Angeles wearing a red and gray oversized flannel shirt, which she wore over a white crop top and a pair of sweatpants, Entertainment Tonight reported.

The Oscar winner, 48, has been spotted multiple times wearing what appears to be the same shirt over the last three years, including this May, Us Weekly noted.

Affleck was not with Lopez when she arrived in L.A. The actor is reportedly in Las Vegas where he is filming a new movie. He was also spotted spending time with Lopez’s mom, Guadalupe Rodriguez, in the city Wednesday.

Meanwhile, Lopez wearing what looked like Affleck's shirt wasn't the first time they have appeared to share their personal mementos. Affleck was also recently photographed sporting the silver watch Lopez famously bought and gave him in her 2002 music video "Jenny From the Block," ET noted.

Affleck and Lopez, who were engaged from 2002 to 2004 before reconnecting in April, have already told their loved ones that they're back together, an unnamed source previously told Entertainment Tonight.

"J.Lo and Ben are very much a couple and have been telling friends that they're together," the insider said. "When they first reconnected, they had to see if the spark was still there because it had been a while. It was, so now they are both fully in it."

An anonymous source also confirmed to Us Weekly that the two are "full-on dating" and "very happy together."

"When they first reconnected, they had to see if the spark was still there because it had been a while. It was, so now they are both fully in it," the source said.

The "Hustlers" star and "Argo" director's romance appears to be getting serious as E! News reported earlier this week, citing an unnamed source, that Lopez is ready to leave Florida and move to California with her 13-year-old twins Emme and Maximilian.

Lopez spent the better part of the last few years in Miami, where her ex-fiancé Alex Rodriguez and ex-husband Marc Anthony are based. Meanwhile, Affleck lives in Los Angeles near his three kids he shares with ex-wife Jennifer Garner.

According to the insider, Lopez plans to move to Los Angeles to be closer to Affleck and has been looking at schools for her children.

"She is excited about a fresh start and pursuing things with Ben. They will be at their L.A. home soon," the source added.
