Actress-singer Jennifer Lopez dressed was smoldering this Halloween when she dressed as a sexy devil for her star-studded Halloween party.

Lopez, a 45-year-old mother of two, posted Halloween photos to her Instagram, showing herself wearing a skin-tight red latex devil outfit, with a plunging neckline. The Mail Online writes that Lopez was joined at the party by 24-year-old rapper Iggy Azalea and 22-year-old singer Demi Lovato. Despite being twice their age, Lopez held her own, looking stunning in her devilishly delightful costume. Made up with smoky black eyeshadow and deep red lipstick, Lopez paired her latex devil costume with a hooded garment, complete with two horns, and fishnet stockings.

The Mail Online also reports that Lopez, recently single again, appeared to attend the party without a date. This past June, Lopez split with boyfriend Caper Smart, a 27-year-old choreographer. While chatting with Maria Shriver on “The Today Show” recently, Lopez revealed her feelings over her relationship with Oscar-winning actor Ben Affleck, who has been married to Jennifer Garner since 2005: “It was probably my first big heartbreak.”

Azalea came to Lopez’s party dressed as a character from “White Chicks,” the Shawn and Marlon Wayans brother’s 2004 comedy smash, while Lovato wore a red wig and a dress with blue polka dots as 1950s comedy legend Lucille Ball. Lopez and Azalea just recently performed a remixed version of their hit single “Booty” during a set at the We Can Survive concert held at the Hollywood Bowl in Los Angeles.

It appears that everyone had a great time at Lopez’s Halloween party and, the next day, Azalea tweeted at Lopez: “@JLo Your party was awesome last night! The dancers! <3.”
