It looks like Selena Gomez and Kendall Jenner are officially back on good terms following their brief feud over Justin Bieber.

According Us Weekly, the ladies attended a dinner party on Tuesday, May 6th at a private residence for Mirtha Michelle's new book release "Letter to the Men I Loved," which was hosted by designer Eli Mizrahi.

A source revealed that during the gathering "Selena and Kendall were friendly."

The insider went on to reveal, "They said hi to each other but sat on opposite sides of the table."

The get together comes just one night after the 21-year-old and the 18-year-old walked the red carpet separately at the Metropolitan Museum of Art's Costume Institute Gala in the Big Apple.

The book release party hosted about 20 guests including the likes of Victoria's Secret model Candice Swanepoel, Maryna Linchuk, Magdalena Frackowiak and Gigi Hadid.

During her time at the party Selena Gomez chatted up Hadid while Kendall Jenner sat with her friends.

The blonde beauty recently split from boyfriend Cody Simpson after a year of dating. Prior to the model the Australian singer dated Kendall's little sister Kylie back in 2012.

Gomez and the Jenner girls were rumored to be going through a rough patch when they were partying at Coachella last month.

The "Slow Down" singer thought Kylie was flirting with ex-boyfriend Justin Bieber during the Indio, California music festival.

Selena Gomez went as far as to un-followed both reality stars on her Instagram account however, the ladies have since put the spat behind them.

A source revealed, "Selena has no issues with the Jenner girls. They had an issue but they have cleared it up," adding, "She has always liked the Jenner girls. They had been fans of Selena since they were young."

Since clearing the air with the pop star, Kendall Jenner has since dined with Bieber, 20, at Manhattan's Nobu 57 while Kylie hung out with the "Heartbreaker" singer when the two attended Floyd Mayweather Jr.'s fight in Las Vegas.
