Three's a crowd! Justin Bieber and Hailey Baldwin are now officially engaged, but he doesn't want the 21-year-old model reminiscing about past times with her ex, Shawn Mendes. The star must have been feeling a little jealous, since he asked his fiancée to delete all her Instagram photos of the pair posing at the Met Gala in May and she happily obliged.

Even though Shawn and Hailey hit the red carpet together at the star-studded event amid dating rumors, it looks like she's completely moved on with Justin. “Shawn is happy for Hailey and Justin and has said that he loves them both, but Justin isn’t taking any chances,” a source tells Life & Style exclusively. “Justin wants to take his relationship with Hailey to the next level, but he can’t do that until he feels confident she isn’t pining for someone else.”

“Erasing every trace of Shawn on her social media was a way for Hailey to prove her loyalty,” the insider added. “And she had no problem pressing delete.” Justin and his wife-to-be announced the big news about their upcoming nuptials on July 10, shorty after returning from their exotic getaway to the Bahamas. They're clearly smitten with each other, as they were all smiles while photographed together in New York City only one day prior.

Despite the fact Justin rekindled his romance with Selena Gomez in early 2018, he's let the world know that Hailey is the one for him. The model has been sporting a ginormous diamond ring and looks happier than ever, especially since Justin recently gushed over her via Instagram. "Hailey I am soooo in love with everything about you," he wrote. "So committed to spending my life getting to know every single part of you." Cheers to a bright future together!
