Beyoncé Knowles and Jay-Z appeared to be each other’s “biggest supporters” this week.

The 31-year-old songstress and the 43-year-old hip-hop mogul have been married since 2008. The couple welcomed daughter Blue Ivy into the world in January 2012.

On Monday night Manhattan royalty came out to celebrate the tenth anniversary of Jay-Z’s New York City venue the 40/40 Club.

According to Us Weekly, it was obvious that Beyoncé was incredibly proud of her man.

"You see that they are each other's biggest supporters," a source told the magazine.

"She was beaming at him throughout the night...That is true love and respect."

When Jay-Z arrived at a VIP booth around 10:30pm he was immediately gifted with “a bow-wrapped box of cigars, a bottle of Ace of Spades champagne, and a stack of $2 bills”.

Beyoncé joined him soon after and a number of celebrities dipped in and out of the booth throughout the night. Kylie Minogue, Fabolous, Maxwell and T.I. all stopped by to congratulate. Apparently proud mother Beyoncé passed along her phone to them all, showing off a cute picture of her daughter Blue Ivy.

At around 2am Beyoncé ordered a round of D’usse Cognac for the party and dedicated a toast to her spouse.

"You should be proud of this milestone," she said referring to 40/40 Club’s decade-long anniversary.

After the toast Beyoncé and Jay-Z hit the dance floor.

Onlookers say they attempted to salsa to Suaveamente, but when Beyoncé “tried to break out the flashy moves and steps” Jay-Z couldn’t keep up.

"It was adorable," the source said.
