One Direction singer falls down caddying for Rory McIlroy (VIDEO)

A whole new generation of tweens just discovered golf this week after Niall Horan of One Direction (just ask any 13-year-old girl) caddied for Rory McIlroy at the Par 3 Contest before the 2015 Masters on Wednesday.

And those same girls probably busted their thumbs tweeting about the pop star's tumble while getting ready for a live interview with reporter Kirsty Gallacher — which went viral.

THE WAY HE FALLS AND THE WAY THE INTERVIEWER SAYS "OH NO NIALL" MAKES ME LAUGH SO HARD https://t.co/87wnsUkvSi

Make your own snarky reference to a O.D. song because I don't know any.

Rams tweet about pop star Harry Styles wearing Michael Sam jersey (VIDEO)

Pop singer Harry Styles was photographed performing while wearing a St. Louis Rams jersey at Edward Jones Dome Wednesday night.

No big deal except this jersey displayed player Michael Sam's name and No. 96.

The choice of fashion was observed as Styles and his One Direction bandmates performed for thousands of swooning, teen-aged female fans — who probably know way more about "Sam and Cat" than Sam the defensive end.

But the British singer's attire didn't go unnoticed by the player or the team.

The team tweeted: Check out @onedirection's @Harry_Styles rocking a @MichaelSamNFL #Rams jersey at the Edward Jones Dome last night.

Sam — who became the first openly gay man drafted in the NFL — tweeted Wednesday '@Harry_Styles thank you for your support!!! #RamNation.'

It's been quite a week for Sam. First, his sack of Johnny Manziel. Then, making the cut down to 75 players. And now, being introduced to a whole new audience. Quite a week.
