Jennifer Lopez, 54, is jaw-dropping in skintight red dress ahead of Christmas… after throwing holiday bash with Ben Affleck

Jennifer Lopez left jaws dropping on Tuesday evening by posting a slideshow of sizzling portraits on Instagram.

The actress/singer, 54 – who hosted a star-studded Christmas party with husband Ben Affleck, 51 – wowed in a figure-hugging red dress as she applied lip gloss in a mirror.

The flirty dress showed off her famous hourglass curves and had an elegant rose embellishment on the collar.

In addition to juicy lips, the Hustlers star's makeup artist Mary Phillips gave her sultry winged eyeliner and applied glossy shadow to her lids.

Her already chiseled features were sculpted with bronzing powder and a vibrant peach blush was dusted onto the apples of her cheeks.

Her honey-colored locks were swept to the side in voluminous waves.

Two of the three photos gave fans a behind-the-scenes look at her glam room.

There is a white director's chair for her to sit in while she gets her hair and makeup done.

Directly in front of the seat is a large mirror and counter area, filled with various products and tools.

Her hairstylist Lorenzo Martin was caught working his magic on the On The Floor hitmaker while handling a can of hairspray.

Jennifer captioned the post with a red heart emoji.

This weekend, the Selena star and Affleck hosted a Christmas party, attended by their closest friends and family.

It was held at their $60 million Beverly Hills home, which they bought in May after a year and a half of house hunting.

According to PEOPLEthe lovebirds invited the likes of Margot Robbie Michael B. Jordan to the soiree on Saturday night.

In a video circulating on social media, Jennifer can be seen in a sparkling green dress while wearing Jingle Bells.

Ben is not featured in the video, but guests are shown alongside a live band with sparkling streamers electrifying the room.

The 12-bedroom, 24-bathroom estate was decked out for the holidays with a huge Christmas tree greeting guests at the entrance and plenty of seasonal decor.

“The kids were all there dancing and having a great time, especially the twins and Violet,” a source said of Jennifer's kids with ex Marc Anthony, 15-year-old Emme and Max, and Ben Affleck's daughter with ex Jennifer Garner, 18 year old Violet.

Jennifer was dressed to impress in two incredible looks: first she donned a long, gorgeous red dress, followed by a blue sequined number.

The couple entertained their own friends separately during their hosting duties, with a source adding that the duo were in “so good spirits.”

Other celebrities in attendance include Ben's brother Casey Affleck, Jennifer Lewis, Lily Rabe and Jennifer's manager Benny Medina.

Earlier that day, Jennifer was spotted doing some last-minute Christmas shopping in Beverly Hills.

This marks Jennifer and Ben's second Christmas as a married couple.

The A-listers tied the knot in July 2022 – just over a year after rekindling their romance in May 2021.

They were separated for 17 years after calling off their first engagement in 2004. Jennifer and Ben subsequently married different people, but both marriages failed.

After falling for each other again, Jennifer wrote and recorded her upcoming album This Is Me…Now.

It is a follow-up to her third studio album This Is Me… Then (2002), which was also dedicated to Affleck.

She said earlier this month Access to Hollywood that the new album “just flowed out of me” and that making it was a “very personal journey.”

Jennifer revealed that Ben actually helped her write part of the visual album and recalled what it was like to work with him.

“It was great,” she cheered. “I mean, no one knows me (and) my story better than him.”

This Is Me…Now will be released on February 16, 2024.
