Adele has prompted speculation she could be pregnant after telling fans she was going to "have another baby".

The Hello singer - who already has four-year-old son Angelo with her man Simon Konecki - has hinted that a new arrival is on the way during a live concert on her current tour of the US.

As she said goodbye to fans in Phoenix, Arizona on Monday, the star dropped the bombshell - although it has to be said she didn't exactly give a due date.

"I'll see you later. I'll see you on the other side," she said after getting the crowd to cheer both her band and herself.

"I'm going to have another baby."

Although fans have been left wondering if Adele is actually pregnant, it sounded more like the singer is planning to have another child rather than already expecting.

It comes days after reports the star - who was just crowned the richest British celebrity under 30 - doesn't want a flashy wedding when she finally ties the knot.

A source said: "Adele said she doesn't want her wedding to be formal and show-off like. She's not tight - she's happy to pay for everyone to have a great day - she just doesn't want it to be stuffy."
