The 'All About That Bass' singer only released her second record 'Thank You' in May, but is already hard at work on the follow-up and she has been getting everyone involved in the process including her best friend/personal assistant.

Speaking to Chelsea Handler about her plans on Netflix talk show 'Chelsea' , Meghan shared: "[I'm] Just writing for the next album. It's like therapy for me."

And talking about songwriting, she said: "Sometimes I'll have my best friend, who's my personal assistant, help me rhyme one word with another, and now she has writing credits on my album. I always need help."

Most recently, Meghan co-wrote the song 'Me Too' for Michael Bublé with Harry Styles and the 'Haven't Met You Yet' hitmaker was full of praise for the pop beauty.

Michael - who has two-year-old Noah and six-month-old Elias with his wife Luisana Lopilato, 29, - said: "Listen, she's a great singer and a great entertainer.

"What [people] may not know is what an incredible writer she is, what an incredible musician she is, [and] the fact that she's a badass producer."

Meghan previously revealed she was left red-faced when she performed a love song in front of Harry, 22, because he was one of the first famous people she ever met.

Of their encounter, she explained: "Performing a love song in front of Harry is terrifying, and on top of that I was a little nervous because he was one of the first celebrities I met."

And getting to work with Michael was a dream come true for the blonde beauty, who had expressed her desire to love to work with him or Bruno Mars.

She previously said: "You know I would love to sing with Michael Bublé or Bruno Mars, I always sing along to their records and I'm like, 'Sounds great! We should do this!' and my mom would always say, 'You and John Legend would sound great together!' So when that happened it was one of those moments like, 'Oh my gosh!'"
