Who is Crystal Leigh? 5SOS Guitarist Michael Clifford Announces Engagement to Longtime Girlfriend

5 Seconds of Summer guitarist, Michael Clifford announced on Twitter Wednesday that he popped the question to his longtime girlfriend, Crystal Leigh.

The two have been dating for three years and the musician got down on one knee during a sunset picnic at the Ungasan Clifftop Resort in Bali — which happens to be the same place where the couple shared their first kiss years earlier — on January 11, according to a Us Weekly report.

With various pictures of special moments throughout their relationship scattered around them, and 1975's "Medicine" played in the background, Leigh said yes to her beau and the gorgeous sparkler.

Clifford posted a series of pictures to his social media, garnering over half a million likes in a matter of hours. Arguably the sweetest picture is Leigh clasping her hand over her face in utter shock — which also displayed a view of the ring.

"You guys are so cute together and have always been the cutest couple," one fan wrote on the guitarist's Instagram. "I'm so excited for you guys! This is amazing."

Later on in the night, the engaged couple had a meal cooked by Australian chef James Viles with friends, according to a report by E! Online.

The two were in Bali to celebrate their third anniversary at an event hosted by retail brand Guess. Leigh seemed completely unknowing of what was about to come, simply posting pictures of her girlfriends and posing in the infamous Bali Swing.

Leigh hasn't yet posted anything on her social media regarding her recent engagement; however, the fashion influencer is most likely busy celebrating the special moment with her new fiance and friends.

The last picture Leigh shared of her and her boo was a retweet from Guess of the duo sharing a kiss in the Bali Swing on the same day as the surprise engagement.

The 5SOS guitarist seemed to hint at a huge moment like this when he posted a picture with Leigh, ringing in the New Year, captioned: "2019 will be the best year of all of our lives."
