Justin Bieber took in the San Francisco sights and spent quality time with his rumored girlfriend, Hailey Baldwin, on Saturday.

Though the couple hasn’t mentioned each other on social media since early January, the relationship appears to be going strong. Bieber blessed us with many photos from their trip to San Francisco ahead of Sunday night's Super Bowl 50.

"She loving the crew," Bieber wrote alongside a picture of himself standing next to the 19-year-old model and many of their friends.

The 'Where Are U Now' singer is credited with another photo of Baldwin, that was shared on Instagram by his friend, Jordan Taylor Wright.

And if you're wondering why Baldwin, who is the daughter of actor Stephen Baldwin, isn't smiling in the photos, it's because she's insecure about her smile.

"People constantly trip out about me not smiling in photos. here's a very simple answer, I'm insecure about my smile! Now leave it alone lol," she tweeted on Sunday.

Meanwhile, Bieber showed off his lack of insecurity about his body. He bared his abs for an Instagram snap that interestingly quoted a famous line from Forrest Gump, "Life is like a box of chocolates."
