Is there a late summer romance blooming between two of music's biggest names?
During one of the songs, "Niall allegedly launched himself" into the "Lights" singer for a kiss.
The new couple was flanked by bodyguards so their offstage sweet moments could be kept as private as possible—and away from festival-goers' pesky camera phones.
It looks like the boy-bander has had a crush on the blond beauty for quite some time.
In a recent interview with GQ magazine, the 19-year-old singer said, "I'll say one thing: Ellie Goulding—wow. She's absolutely amazing looking."
Whoa there, tiger!
A source tells E! News, however, that Goulding is still with her boyfriend Jeremy Irvine and that there is "no truth" to the romance rumors.
"She and Niall are just friends," the insider added.
On Aug. 13, Horan tweeted to fans to rally up support for Goulding's latest single, saying, "Everyone my good friend @EllieGoulding Has a huge tune out right now! And I really want her t get #1, go get it"
What a supportive friend…no, but seriously.
And just take a gander at their flirty banter back in July where Horan wrote, "Just listening to some @elliegoulding! What a talent she is! Beautiful voice !"
To which she coyly responded, "I knew you loved me hahaha"
Meanwhile, Horan isn't the only one who is seeing his love life heat up.
When asked whether it was public knowledge, he said, "Well it is now! It's new, she's sitting right over there. It's not been long."
Clearly it's been quite a fun summer for these Brit boys!
