Social media champions: Selena Gomez, Vin Diesel on top, sorry Kylie

Vin Diesel is the third most-liked star on Facebook

With just under 100 million likes, he has double the likes of US President Barack Obama.

That also makes him the third most-liked star on Facebook, sitting behind Shakira at 104 million and footballer Cristiano Ronaldo right at the top with 110 million likes.

Selena Gomez is the most-followed person on Instagram

This month, Selena finally eclipsed pal Taylor Swift to become the most-followed person on Instagram, with 69.4 million to Taylor's 69.2 million followers.

Nude selfie queen Kim Kardashian is a sad third with 63.7 million Kim loyalists.

Katy Perry leaves Taylor Swift out of the woods on Twitter

Katy Perry is the most-followed person on Twitter, with 84.4 million.

Her rival Taylor Swift sits at 72.8 million followers, comparatively. Over on Instagram, Taylor has 74.4 million followers – just over three million more than Katy.

Liam Hemsworth has more Facebook likes than Chris Hemsworth

The Hunger Games hottie and on-off Miley Cyrus lover has 7.3 million FB fans to his Thor-some brother's 4.9 million.

On Instagram, Liam wins again with 3.1 million followers to Chris' 2.8 million.

Kanye isn't the most popular rapper on Twitter

Kanye West might rant daily about corporations, fashion, Taylor Swift and himself to his 20 million Twitter followers, but he's left in the shadow of a bunch of other rappers: Drake (29.6 million), Lil Wayne (26.1 million), Wiz Khalifa (24.4 million) and even Pitbull (21.8 million).

The One Direction boys are still doing better than Zayn

Zayn Malik's solo career may have taken off with his huge single 'Pillowtalk', but on Twitter he's still trailing each member of his former band One Direction with 8.2 million.

Harry Styles, the next most likely solo star in the band, takes the top honour with 27.5 million followers.

Kylie Jenner is SO NOT popular on Facebook and Twitter

Kylie Jenner's lips are a big deal on Instagram (54.3 million care about them), but they're somewhat deflated on Facebook and Twitter.
