Mariah Carey is pregnant with twins and Obamas were the first to know

It’s official now. After all that denying, Mariah Carey's husband Nick Cannon has finally confirmed that the couple is expecting twins.

And who managed to get the news out of the star couple? US President Barack Obama and first lady Michelle Obama.

A radio DJ told listeners of his radio show ‘Rollin With Nick Cannon’ on Thursday that they were having twins and the president and his wife were the first to be privy to the secret, reports the Daily Mail.

He said Carey spilled the details when the Obamas asked her about the pregnancy backstage at TNT's ‘Christmas in Washington’ last Sunday.

“They, ironically enough, questioned my wife about, you know, "So, what are you having, are you having twins?’” he said.

“And at this point she hadn't told anybody anything because doctors advised us to keep it to ourselves until we get further along,” Cannon added.

“And because of the excitement, because of the emotion, she was overwhelmed [and] she shared with the president and first lady that we are having twins.:” the singer said.

In a recent radio interview, Carey, 40, had referred to her unborn child as ‘they’, saying, “I just hope that they don't turn out hating Christmas”.

The reference to ‘they’ had the rumour mill buzzing that the couple might be expecting twins.

But last week, Cannon was attempting to cover up the slip-up, explaining that Carey used the plural term to cover both male and female sexes.

But thanks to the Obamas, the cat is now well and truly out of the bag.

Carey said she had been ‘excited’ to share the news with the president and the first lady and it had been a ‘very special moment’.

The twins are expected in the spring, but the couple have not revealed the babies’ due date.
