Hillary Clinton and Mariah Carey have exchanged backstage photos of each other from Barbra Streisand's Madison Square Garden concert last weekend.
"An honor to meet President Clinton and her husband, former President Bill Clinton!" pop star Carey, 50, tweeted Monday with a smiley-face emoji, jokingly referring to former first lady, former New York senator and former Secretary of State Hillary Clinton, 71, who won the popular vote in the 2016 presidential election.
Hillary Clinton responded Tuesday with a tweet saying of five-time Grammy Award-winner Carey, who was born in Huntington and raised in Greenlawn, "The honor is ours; it's not every day you meet a queen."
Music and screen legend Streisand, 77, also gave social-media props to the Clintons, captioning an Instagram photo of herself with them, "So honored this brilliant couple attended my concert in New York. The only President in the last 50 years to leave our country with a budget surplus. He also banned assault weapons, which the Republicans then overturned."
She included Carey in a collection of photos of herself posing with concert guests including comedian Billy Crystal, who was raised in Long Beach, and comedian Rosie O'Donnell, a Commack native.
Carey posted a photo of herself backstage with Streisand, writing across her social media, "A LEGEND. Thank you @BarbraStreisand for a magical evening."
Meanwhile, on Tuesday, Streisand brought out Ariana Grande for a duet at her Chicago show to perform the duet "No More Tears (Enough is Enough)."
Grande, 26, reportedly was left in tears after the performance.
Streisand posted several images of the two backstage, captioning an Instagram post including a photo of the two standing next to each other: "Secret's out. Thank you @arianagrande."
Grande posted the same image in black-and-white to her Instagram account, captioning the photo, "cherishing this moment forever @barbrastreisand." The junior singer also posted video of the two performing Tuesday night.
