Cosy: Justin Bieber and Selena Gomez after leaving his grandparents' house today
It would take a hard heart not to be charmed by the burgeoning romance between teen behemoth Justin Bieber and Selena Gomez.
The pop juggernaut, 16 , and the Disney starlet, 18 , seem to be going from strength to strength after pictures of them holidaying together in St Lucia in the Caribbean finally confirmed their relationship beyond doubt.
Today they were spotted leaving Justin's grandparents' home in Stratford, Ontario, signalling that their affair is becoming yet more cosy.
It comes a day after pretty Gomez cheered on her soccer mad beau during a kickabout, in an adorable display of young love.
The twosome have been spotted around the town enjoying each other's company, and that of Justin's family.
They enjoyed a low-key meal at the town's Pour House with Bieber's father, aunt and nephew.
It was reported that the down-to-earth party feasted on burgers and chicken wings, before Justin and Selena hit the jukebox.
But there is a sinister side-effect of their romance.
Gomez has received a string of death threats after she was pictured kissing Bieber during their holiday.
Justin's fans, who are popularly known as 'Beliebers', posted several hostile messages to the star's Twitter account.
Family: Bieber has ensured Selena is spending plenty of time with his kin
One message read: 'Roses are red, violets are blue, @selenagomez if you'll break @justinbieber's heart I'm gonna kill you'.
Selena and Justin have been keeping very close company in recent weeks.
They enjoyed pancakes at American chain restaurant, IHop pancake house in Philadelphia, and they were snapped warmly embracing after Selena attended Justin's sold-out concert at the American Airlines Arena in Miami.
Speaking to Us Weekly, Selena denied any type of romance insisting that they two were more like brother and sister.
No doubt: The couple hand in hand earlier this month
'It was pancakes! Oh my gosh! [Justin is] one of my best friends…' she mused.
'Who doesn't like pancakes? We were both performing in the same place so we went and had pancakes together. That's all it is. All innocent.'
Selena also explained her feelings for Justin, describing him as 'family'.
'I love Justin. When he first started to come over from Canada his manager contacted me and he just said that he would like to meet me and he was just such a good kid…' she said.
'I feel like a big sister now, because I want to protect him.'
