Last week, they renewed their wedding vows in a romantic Parisian setting four years on from when they tied the knot.
But on Monday, Mariah Carey and Nick Cannon have another milestone to celebrate – the birthday of their twins Monroe and Moroccan.
The fourth time newlyweds looked like loved-up teenagers as they kissed and cuddled on the streets of Paris before flying to Austria on a private jet with their now one-year-olds.

The diva popstar tweeted about the day during a shopping trip on Sunday, writing: “Shopping for Roc & Roe’s bday in Paris…Dembabies, dembabies,dembabies!”
“We have put together some very festive plans!”
The famous couple had opted for full-on romance when they took their vows once again in the City of Light – in one of the annual traditions that keep their love alive.
With a stunning view of the Eiffel Tower in the background, the TV personality went down on one knee to ask the songstress to become Mrs Nick Cannon all over again.
Mariah was dressed for the occasion in a white fishtail gown that accentuated her every curve, and Nick was matching in a white suit.
The fun celebrations were a contrast to their real wedding in 2008 when they slipped away for an ultra-private ceremony on Mariah's estate in the Bahamas.
