Justin Bieber celebrated his 25th birthday on Friday as his wife, Hailey Baldwin, took to Instagram to honor his special day. Hailey posted a short gallery with two photos of the young stars looking loved up [2] and embracing each other. In one picture, Hailey snuggles up to her husband while the other snapshot shows the lovebirds holding each other as the 22-year-old model [3] laughs (with her gorgeous wedding ring [4] in sight). She then captioned the post, "25 sure looks good on u lover."

Hailey and Justin have continued to maintain a rather private romance [5], following their super secret September wedding [6]. However, they opened up about their relationship [7] in the March issue of Vogue, where they graced the cover and were featured in a stunning spread [8]. They shared their thoughts [9] on what it's like being newlyweds, emphasizing that marriage isn't always perfect [10], but it's worth it. "I'm not going to sit here and lie and say it's all a magical fantasy," Hailey said. "But there's something beautiful about it anyway — about wanting to fight for something, commit to building with someone." Justin — who proposed to Hailey [11] during a trip to the Bahamas — additionally expressed his commitment to his spouse and their relationship, adding, "With the lifestyle I live, everything is so uncertain. I need one thing that's certain. And that is my baby boo."
