The music stars, whose duet Senorita has been a number one hit this summer, are reported to have started dating earlier this year, although they have yet to officially confirm their relationship status.
Asked what it was like working together on the song, Cabello told Capital Breakfast: “Well it was so fun! You know, we’ve been friends for a really long time and we were kinda like we just didn’t…
“There was a period where we didn’t hang out as much just because we were both busy and this song was really fun because we got to just hang out again like we did on the song we did before – I Know What You Did Last Summer – which was when we got really close.
“This was just like we were like ‘oh yay, we get to be pals and just hang out!”
The Cuban-American pop star added: “Yeah. Yeah, we’re pretty happy, I really, really love him a lot.”
There has been plenty of speculation about their romance in recent months, and Cabello, 22, and Mendes, 21, have done nothing to ease the rumours.
Shawn and Camila first met when he served as an opening act for Fifth Harmony on tour back in 2014, and just recently started dating over the summer.
