Justin Bieber and wife Hailey Baldwin might be married, but that doesn't mean they can't flirt and be playful with each other.

Over the weekend, Bieber, 25, stepped out for an outing with his 22-year-old model wife in Orange County, and the couple looked very happy and in love. The singer flirted with Baldwin and even slapped her rear as they enjoyed a day out together, according to Daily Mail.

In photos from their outing, Bieber looked much happier and healthier in his white sweater, matching loose pants, orange beanie and yellow and white checked shoes. Baldwin, on the other hand, donned a simple but chic outfit, wearing a stone maxi dress with a slit on one side, large hoop earrings and white sneakers. She styled her hair in a high bun and completed her look with a black sling bag.

One photo showed the couple entering a boutique, while other snaps featured Baldwin and Bieber holding hands as they strolled along Orange County. Bieber and Baldwin were also seen tucking into cold treats as they shared laughs and playful banter.

But this isn't the first time Bieber and Baldwin have been spotted goofing off with each other. Even before they tied the knot in September last year, the couple have always had a playful relationship.

Back in December 2015, Bieber gave Baldwin a "wet willy" when they went on a Caribbean getaway with the singer's family. A video he posted on Instagram showed him licking his finger and then sticking it in the then-19-year-old model's ear, surprising her.

This latest sighting of the couple comes a few days after Bieber and Baldwin moved into their new mansion in Beverly Hills.

The model shared a few photos of their new $8.5 million home on her Instagram on Thursday. One snap showed Bieber leaning on the island of their mostly bare kitchen. Another picture revealed Bieber and Baldwin's bed with two sets of thick pillows.

Meanwhile, Bieber is currently seeking help for his mental health struggles, including anxiety and depression. A source close to the "Love Yourself" singer told People that Bieber has not detailed his personal struggles nowadays because he has received backlash over it in the past.

“A couple of years ago, Justin publicly talked about the medication he was on, and there was backlash,” the insider said. “Everybody has an opinion about mental issues and medication, and he was condemned for doing what he thought was right with the help of his doctors. You should have seen some of the tweets that were directed at him, and the messages he got.”

“He hasn’t recently gone into the specifics of what’s going on with him, because he’s in a no-win situation,” the source continued.
