Adam Levine gushes over his wife in a photo shared on her 30th birthday

Adam Levine paid tribute to his wife, Behati Prinsloo, on her 30th birthday.

In a touching Instagram post on May 17, 2018, the Maroon 5 singer and The Voice coach called her 'The Queen'.

Levine has two children with the former Victoria's Secret angel, whom he married in 2014.

He shared a photo of his wife in a playful pose on Instagram. He wrote beside the photo: 'She's a legend. She's THE baddest. In just a few years we have laughed and loved harder than most. I wake up every morning thankful it wasn't all a dream. Here's to a thousand more years. I love you @behatiprinsloo with everything I got.'

In the photo, the model is wearing retro white sunglasses, a white T-shirt and blowing a red plastic whistle.

In just a day, the post has generated almost 700,000 likes.

Many Instagram users expressed their adoration of the couple in the comments section. They also greeted Prinsloo happy birthday.

Prinsloo and Levine married in July 2014 in Mexico, two years after they started dating. They now have two daughters.

The model gave birth to their first child, Dusty Rose, in September 2016. A year later, Prinsloo announced her second pregnancy on Instagram. She and Levine welcomed their second daughter, Gio Grace, on February 15, 2018.

In an interview with PEOPLE in 2017, Prinsloo opened up about the joy of being Levine's husband and being a mother.

"I love Adam, and when you get married and you fall in love with someone, you think that there's no greater love than that love. And then you have a baby, and it's just next-level love," she said.

She admitted that she also faced struggles commonly experienced by mothers, such as lack of sleep for taking care of her child. But she said all of it is worth it.
