Selena Gomez, Justin Bieber Spend New Year's Eve In Cabo

The pop stars rang in 2018 together.

According to E! News, Justin Bieber joined Selena Gomez in Cabo San Lucas, Mexico on Sunday, Dec. 31, 2017, just in time to celebrate the new year.

The "Sorry" singer shared a snapshot of himself with two friends at their shared villa on his Instagram Stories, and he was also photographed on the beach earlier in the day. As E! News noted, Gomez and Bieber have actually vacationed in Cabo together before.

"Justin and Selena are doing great," an insider told People, confirming, "They celebrated New Year's Eve together in Cabo." However, at the time of this writing, the infamous exes have not yet been photographed together.

As Nicki Swift previously reported, the "Bad Liar" singer jetted off to the resort last week, renting out an $18,000-per-night luxury villa with three of her best friends, Ashley Cook, Courtney Barry, and Raquelle Stevens.

"Our 6th New Years together!" Stevens wrote on Instagram on Friday, Dec. 29, sharing a fun snapshot of the four posing on the beach together. "Grateful for so many amazing memories. ☀️💗." In the pic, a smiling Gomez, who recently announced that her new album will drop "very soon," wore a black one-piece, making peace signs with her hands in the air.

"She seemed very excited when she landed and was giggling with her friends and taking photos," an E! News source said at the time. "They are all planning to do some fun dinners and spend New Year's Eve together."

Gomez, 25, and Bieber, 23, dated on and off between 2011 and 2015, but they recently reconnected after the "Wolves" singer opened up about her kidney transplant earlier this year. The two have since been spotted together multiple times and are rumored to have rekindled their romance. They most recently took a private jet to Seattle for what appeared to be a date night.

While we wait to hear more details from their New Year's vacation, read up on what's really going on between Selena Gomez and Justin Bieber.
