John said he was inspired to join forces with Spears by his husband, David Furnish, adding that he believes their duet will give her a much-needed confidence boost after such a “traumatic time.”
A quick scan of social media and it looks like fans are delighted by the joint release.
“Such a cool, beautiful song, you guys make a wonderful team! We have missed you so much Brit, you can’t imagine how happy it makes me to hear you singing again,” one fan wrote on Twitter.
Another said: “welcome back!!!! Hold me closer is freaking fantastic! You sound so good!”
