Meghan Trainor claims installing side-by-side toilets is the "best thing [she] ever did"

Speaking on 'The Tonight Show Starring Jimmy Fallon', she said: "My mom's like 'I wish there was a song attached to this.' But there's not.

"I didn't know it was going to be such a big deal, that's why I casually brought it up on a podcast.

"When we moved into this new house, and, you know, you get up all throughout the night with a baby, and you got to pee. There were so many moments where I was like 'Move, I have to go,' so when we moved to this new house I was like 'I have an extra toilet, can I just pop them next to each other?'

"The plumber giggled and I was like 'I don't see why you're laughing.' Like, just do it, get it done.

"And they did it, and it's the best thing I ever did."

And Meghan insisted the unusual bathroom layout is the best thing about her house.

Asked if she'd change it if she could, she replied: "You know how expensive it would be to change that? No, this is the best thing about my house. It's my favourite part of the house."

After recently causing a stir with the news of her two toilets, the 27-year-old singer took to Twitter to clarify she and the 'Spy Kids' actor don't "poop together" - but her husband will "hang out" with her in the bathroom when nature calls.

She wrote: "To clear things up...we pooped ONCE together and we laughed and said never again...but he will hang out with me if I'm [poo emoji]ing cuz WE SOULMATES. And i legit miss him when I'm away from him. And we pee together obvi.(sic)"
