The 55-year-old actress and singer rocked a sport ensemble that put the spotlight on her trim tummy as she deplaned.

She was arriving back in Los Angeles after a trip up north to the Toronto International Film Festival for the premiere over the weekend of her new film Unstoppable.

The awkward event featured Lopez and one of the film’s producers, Matt Damon — who shared an intimate conversation with the actress — but her estranged husband Ben Affleck skipped out on the premiere.

Although her outfit on Monday appeared to cover up the sides of her torso, Jennifer’s revealing dress on the TIFF red carpet left fans wondering if she had gotten a ‘commitment’ tattoo removed, after she and Ben got complementary ink.

The Out Of Sight star’s travel ensemble featured a low-cut white cropped tank top with spaghetti straps, which highlighted her age-defying flat stomach and trim waist.

She made the look slightly more modest with a pale gray sweatshirt that she wore draped over her shoulders, with the sleeves hanging down her front.

Jennifer stayed on point with a matching set of pale gray low-rise sweatpants.

Instead of athletic shoes to match her low-key look, she opted for a pair of off-white sneakers, and she kept her caramel-colored hair styled simply with a messy bun.

J.Lo appeared to display a more minimal makeup look than usual, and she blocked out the light with chunky black sunglᴀsses.

After she descended from the private jet, her ᴀssistants ushered her to a black SUV before driving off.

Jennifer’s revealing tank top should have exposed her ‘commitment’ tattoo that was debuted early last year at the height of her romance with then-husband Ben Affleck.

She had the ink placed high up on her left rib cage, so it is usually covered by her clothing.

A pH๏τo Jennifer posted to Instagram revealed that the design featured an infinity-like symbol with an arrow shooting through the two loops.

It complemented a tattoo Ben got that she also posted.

His ink showed two crisscrossing arrows that appeared to be tied together at the junction.

Her initial, ‘J,’ was inked above the crossing point, and Ben’s last drawn below it to symbolize their marital and romantic bond.

However, when Jennifer posed in a stunning dressed covered front and back in sparkling mirrors at the Toronto International Film Festival, the tattoo didn’t appear to be visible.

The dress featured separate front and back sheets of mirrors, and they were tied together with thick bows over her sides that left little to the imagination.

But there wasn’t any obvious sign of the eternity symbol on J.Lo’s exposed rib cage.

It’s unclear if she had already started the process of getting the tattoo removed or if she had simply covered up the ink with makeup for the time being.

During Jennifer’s time at TIFF, she was spotted having an intimate conversation with one of Unstoppable’s producers, Matt Damon.

They were seen clasping hands and sitting during some down time.

Matt and his longtime friend Ben had produced the film together, but the Gone Girl star opted to skip the Toronto premiere to remain in Los Angeles with his children.

Despite how J.Lo and Matt appeared to be having a heart-to-heart in pH๏τos of the event, an insider told DailyMail.com that the Ocean’s Eleven star ‘shut down any attempt’ that Jennifer made to bring up her estranged husband Ben.

‘It was her timing that was so awkward because she would have known that pulling Matt aside at the event to have an intimate talk was going to get picked up and go viral,’ they added.

The insider stressed that Matt would ‘always have Ben’s back no matter what,’ and they clarified that he was not praying with Jennifer, after some fans interpreted his bowed head as a shared prayer.

Jennifer was seen at the premiere and with Matt while wearing the sizzling ‘revenge dress’ to celebrate her first red carpet event since her divorce filing.

She filed the paperwork last month, citing ‘irreconcilable differences’ as the reason for the split.

Although she was the one to file, and Ben appears to have opted not to do so, he was reportedly well aware of her plans.

According to an insider, the estranged couple had agreed on the divorce terms before she filed, and neither party was looking to surprise the other.

The reporting is largely in line with the couple’s decision to fake a healthy marriage for months with occasional public outings together, despite having already split behind the scenes.

It’s unclear if the two had a prenuptial agreement in place, which wouldn’t have been noted in the divorce filing, though it appears that the main sticking point for the two independently wealthy people will be their Beverly Hills mansion, which they have now put on the market while Jennifer searches for a new home.

Ben has already moved into a more modest home in Brentwood, close to where his ex-wife Jennifer Garner lives, which will make shuttling their children back-and-forth simpler.
