Kelly went on to praise the item and insisted it also made a “really good birthday present” for friends.
The same morning Kelly revealed during an interview on KIIS FM’s Kyle & Jackie O Show that she loves stripping off in her backyard.

It comes after The Voice coach shared with PEOPLE magazine last month how she and her husband Tim Weatherspoon keep the spark alive in their marriage, now that they have been married since 2014 and have a five-year-old son named Titan.

"When we met each other, we had fun. Two years from now, we’ll have fun. I think if you hold that close to you, it can always show itself in your relationship.”
