That's a BIG apology! Nick Cannon gives Mariah Carey a diamond bracelet for her birthday... two days after bragging about sex with Kim Kardashian

It can't get much blingier: Nick Cannon bought Mariah Carey a diamond encrusted bracelet for her birthday, two days after dishing the dirt about sex with Kim Kardashian

Talking publically about sex with your wife is one thing. Revealing details about sex with your ex-girlfriends is quite another...especially if one of them is Kim Kardashian.

Maybe that's why Nick Cannon bought Mariah Carey a hugely blingy diamond bracelet for her 45th birthday today, two days after telling all about their wedding night and his torrid time with Kim.

The rapper's mouth ran away with him in a radio interview with Power 106 host Big Boy on Tuesday. The station posted the full video of the no-holds-barred chat, with all the details it couldn't broadcast on air.

Loved up couple: Both Mariah and Nick posted this cute shot on social media sites and Nick captioned it, 'Yep She's Happy!!!!'

Look what I've caught: The 33-year-old posted this snap on Thursday saying: 'I'm taking this one home with me! #keeper #Angel #Unconditional #Agape #MyJoy He who finds a Wife, finds a good thing.'

Whaaaaat! Radio host Big Boy was shocked when the rapper shared his celebrity sex secrets with him

My little princess: Nick posted this photo of Mariah taken on her birthday when she was a child for Throwback Thursday. He captioned it: 'Happy 3/27!! It's officially a party!!! The love of my life @MariahCarey #WWLD'

Aside from shocking Big Boy with his long list of exes, Nick also decided to spill details - and lots of profanity - about the first time he and his wife Mariah slept together.

'[The first time was] on our wedding night, honeymoon style in a house in the Bahamas. That's a real woman right there to make you wait.'

But he was not done. Describing his wife of six years as his 'soul mate,' he gave more details.

'I'm a pleaser. I went in going, ''She going to love this''.... I f****d the s**t out if her,' he said.

After being so vulgar - and seeing the surprised look on Big Boy's face - the 33-year-old realised his wife may not be so pleased with him when she heard the interview.

'I can hear the conversation now, ''Why are you being so crude and nasty talking to Big Boy?'''

A really big birthday present was the ideal way to make amends, if any were needed. And it worked.

Mariah posted two shots of her blingy bracelet on Twitter. The first was captioned: 'Nick surprised me for 3/27 with a stellar diamond bracelet encrusted with 3 floating butterflies! @NickCannon pic.twitter.com/kZiGnDFXbX'

The second showed a smiling Nick cuddling up to Mariah's bling-covered arm as she leant her head on his.

Nick's own commentary on Instagram, where he posted the same two photos, went: 'I think she's happy...' followed by  'Yep she's happy!!!!'

He also posted a cute snap of him sweeping the singer off her feet, quite literally, with the caption: 'I'm taking this one home with me! #keeper #Angel #Unconditional #Agape #MyJoy He who finds a Wife, finds a good thing.'

The loved up couple, who will celebrate their sixth wedding anniversary on April 29, have twins, Monroe and Moroccan, who will be three next month.

The celebrities put their babes safely to bed with sitters and went out to celebrate Mariah's birthday and the Seminole Hard Rock Hotel & Casino Tampa's 10th anniversary.

The intimate setting was the casino's Plum VIP Lounge, with 50 guests.

To mark the occasion, Mariah donated a dress from her No. 1 hit Obsessed music video to the Hard Rock Memorabilia collection.

She also cut a special anniversary cake baked by the casino's pastry chef Alon Gontowski.  

Meanwhile, to celebrate Throwback Thursday, Nick posted of photo of Mariah taken at a birthday when she was a child, saying: 'Happy 3/27!! It's officially a party!!! The love of my life @MariahCarey #WWLD'
