Jennifer Lopez stunned in a sizzling gown that accentuated her curves while flaunting her toned stomach and underboob.

Revealed: The 45-year-old vocalist shared with Giuliana Rancic her disappointment over the conclusion of American Idol, citing her strong connections with the show’s staff as a major factor.

When do you think the wedding will be happening? J-Lo gave Smart an affectionate glance as he chatted animatedly; rumors are circulating that they are in the process of planning their nuptials.

You bet! During the performance, Jenny and Casper Smart were seated next to each other but did not display any public displays of affection.

They are also collaborators: They appeared together in the Dance Again video and both contributed to the song Home; here she casually twirls a ring on her left hand.

He’s definitely a tactile person: the choreographer casually rested his hand on the knee of the Booty singer while she clapped.

In a quick change of events, Casper was no longer around, and Lopez was spotted at the event sitting with her manager Benny Medina. Noticeably in the background was Kylie Jenner. Reflecting on her time at the event, the talented Jennifer Lopez shared, “It was an amazing experience for me. I truly enjoy meeting new people and going on this journey.” Making a solo entrance to the event, Lopez hinted to Rancic that perhaps her beau would make an appearance later in the evening. Despite rumors of rekindling with Casper for months, J-Lo’s former flame arrived in a dark suit after her appearance on the red carpet. During the show, the two sat together but kept their affection private. At one point, however, Casper’s gaze lingered on her chest.

The conclusion of a significant chapter: ‘The whole experience has been truly wonderful for me; I have a deep affection for the people I’ve worked with, the journey we’ve been on, and the friendships I’ve made,’ shared the AKA singer about her time on the Fox show. Jennifer appeared at the Billboard Music Awards to represent Finding Neverland The Album, where her duet with Trey Songs, titled What You Mean To Me, is included. Speaking about the musical, she expressed, ‘Finding Neverland is a beautiful production. The collaboration with Trey is a personal favorite of mine, and the album boasts exceptional artists such as Christina Aguilera and John Legend. It’s a fantastic soundtrack.’ Reflecting on her upcoming Las Vegas show, she mentioned admiring other performers and cited Shania Twain and Britney as inspirations. ‘I’m excited to deliver an exhilarating, high-energy show,’ she added. The shows are scheduled to commence in 2016 at Planet Hollywood.

In 2016, when it came to her Las Vegas performance, she mentioned taking cues from other artists. She specifically cited Shania Twain and Britney Spears as her sources of inspiration.

No significant other: The resident of The Bronx mentioned during the interview that she could be attending the event with a special companion but preferred to keep it a mystery.

Hey there, look who’s here: The actress from Maid In Manhattan, accompanied by her publicist, made quite an entrance on the red carpet.

Attention! Smart was nowhere to be found when The Boy Next Door star engaged in some playful banter with rapper 50 Cent on the red carpet.

The guy that has her heart: Her young beau Casper showed up after her; they still haven’t announced if they’re sharing a living space.

During the event, the presenter who made the I Luh Ya Papi reference witnessed Taylor Swift and Sam Smith emerge as the standout winners of the night.

Two vocalists hit it off: Lopez paused for a photo opportunity with British singer Rita Ora.
