The celebrity couple are often paying sweet tributes to each other on social media, and last month Blake posted a cute photo of them hugging on the beach, which had been taking from their Happy Anywhere music video. "I could be happy anywhere with you," he wrote alongside the image.
Happy Anywhere was released in July, and marked the second time that Gwen has featured in one of Blake's songs.

The single was accompanied by a music video comprising of clips of the couple together during lockdown at home and outside on the ranch in Oklahoma, where they stayed for several months.
Gwen and Blake had previously teamed up to sing Nobody But You in December, and performed it live during Blake's Friends and Heroes tour earlier in the year before lockdown took place.

During a previous appearance on the TODAY show, Gwen opened up about just how much Blake helps out with her sons, while chatting to host Hoda Kotb.
When asked if she thought he would make a good father, she replied: "He is a good dad, actually. He's been helping me out a lot, so I literally get to the point where I'm like, 'You gotta get home, I need help.' So it's hard. I got three boys."
