The pop star protege of Justin Bieber kept by her man's side, as they walked hand-in-hand through the Florida sand.

Madison skipped the cosmetics, allowing her flawless complexion and natural beauty to shine through. 

Her hunky 20-year-old beau was dressed comfortable in black and white printed swimming trunks.

His dark mane was slightly disheveled, adding to his boyishly handsome good looks.

The handsome duo shared a warm embrace as Jack wrapped his arms around Madison, and sweetly kissed her along their walk.  

Madison and her boyfriend, half of the singing duo Jack & Jack, were first linked in January 2015, when they were spotted at a diner together.

Two months later they were pictured at the Comedy Central Roast of Justin Bieber together in March and Gilinsky confirmed the couple were an item the following month. 

Madison rose to fame in 2012 when pop sensation Justin Bieber, 22, tweeted a link of a YouTube cover she did.

She eventually was signed to the Baby singer's label, Def Jam Records.

Like Justin and his girlfriend, boyfriend Jack has the internet to thank for his success.

The singer became famous courtesy of six-second Vine videos he posted with friend Jack Johnson.

Since then, he has had the chance to see the world, courtesy of the duo's tours.
