Beyoncé and Jay-Z pick up some tips as they show support for Erica Reid's book The Thriving Child at launch

As first time parents, the thought of raising a child to be healthy and happy can sometimes be a daunting one.

And last night Beyoncé and Jay-Z proved that even celebrity parents turn to parenting manuals and guide books for advice, as they attended the launch party for friend Erica Reid's book The Thriving Child.

Beyoncé showed off her stunning post-baby body in a form-fitting teal dress, highlighting her tiny waist with a thin belt for the occasion, while husband Jay-Z in a printed T-shirt and denim jacket.

The 30-year-old singer, who welcomed Blue Ivy, her first child with Jay-Z, in January, left her blonde hair down and straight for the event, pairing her outfit with a pair of hoop earrings.

The pair looked more in love than ever at the party, held at a private residence in New York, with Jay-Z smiling as he playfully pinched his wife's cheeks while the pair posed up for photographers.

Beyoncé and Jay-Z were joined at the event by other famous faces including Mary J. Blige, with the two female singers pulling in author Reid for a tight hug at the event.

Jay-Z and Beyoncé just can’t seem to keep their loving hands off each other! The new parents attended a book launch in NYC last night, in support of Erica Reid’s latest, The Thriving Child. Erica is the wife of music mogul L.A. Reid, and her book chronicles her experience raising two kids with allergies and asthma. In addition to Erica’s journey, it also includes advice from top medical professionals and other celebrity moms. Blue Ivy’s Aunty Mary J. Blige was also on hand for the launch.

Reid, the wife of X Factor USA judge L.A. Reid, decided to pen her bestselling book The Thriving Child: Parenting Successfully through Allergies, Asthma and Other Common Challenges after discovering that both her son and daughter suffered from serious allergies and irritations since birth.

Reid, who is mother to 11-year-old daughter Arianna and eight-year-old son Addison, said in a recent interview that she believes in a firm but fair approach to parenting.

She said: 'I love my children, I am very sweet to them but I'm also very firm with them, and they don't get their way with every single thing.

Clearly being super playful and affectionate is what got Jay-Z and Bey little Blue in the first place. Hopefully they snapped up a copy or two of Erica’s book to keep on hand for the child rearing lessons in their future. The Thriving Child is available on Amazon.

Team Blake's Jermaine Paul is crowned winner of The Voice.

Alicia Keys' former backup singer has finally been given his time to shine.

Jermaine Paul, Team Blake's consistently competent R&B singer, was crowned as winner on tonight's season finale of The Voice.

His victory was surprising only in the fact that it was anticlimactic, as he has been considered one of the front-runners all along.

Coach Blake Shelton couldn't have looked happier to hear the results Paul and Shelton hug it out on The Voice stage

He believes: Jermaine's wife stood by his side as he sang 'I Believe I Can Fly'

The final four: Jermaine Paul, Chris Mann, Juliet Simms and Tony Lucca.

But, as coach Blake Shelton said, Paul deserved to win 'because of his talent. He's figuring out what he wants to do, and he can do anything.'

Paul was understandably emotional after having been relegated to backup singer status for so many years.

The singer got emotional while saying: 'I just wanted to say thank you to everyone that voted for me. God bless y'all, man. Nobody but Jesus, man, nobody!'

After thanking the Lord, he also remembered to thank his wife, children and parents.
