Meghan Trainor wants to ''lock'' her fiancé down as soon as she can.

The 'All About That Bass' hitmaker can't wait to tie the knot with Daryl Sabara and whilst they don't have a date set yet, she wants to do it as soon as possible.

When asked about wedding planning, she gushed on The Today Show: ''I mean, I don't know when or where, but we're going to do it. I'm locking it down. He's mine.''

Meanwhile, the 24-year-old singer previously admitted she knew she wanted to spend the rest of her life with her fiancé from ''week one'' of their relationship.

When asked about the moment she knew Daryl was the one she wanted to marry, she shared: ''Week one. I was a little aggressive. We said 'I love you' week one, it took a minute and he said something like 'I'm enamored with you' or whatever and I was like 'what does that mean? Just say it!'''

And Meghan has never loved ''any other human'' as much as she loves Daryl, and enjoys spending every day with him.

She told BANG Showbiz: ''It's that cheesy line of 'You know when you know' and that's so real because I've never had anything like this with any other human, I've never not got sick of someone. I've been with him literally every day and I'm not sick of him, and I miss him when he's not in my visual sight, its gross.''
