"We've been 'off and on' together for a couple of years now and we just kind of made it official," she said on The Talk about her and Brooklyn's decision to go public with her relationship.

"We were always running from paparazzi ... it [was] affecting our relationship ... we were like, if we were more upfront about it ... and just let them take our photo - they aren't going to care," she added.

Chloë, 19, and Brooklyn, 17, first met at a SoulCycle class in 2014 and sparked dating rumors after being spotted together at the Teen Choice Awards later that year.

The couple had initially maintained that they were just good friends but The 5th Wave actress officially confirmed that they were in a relationship on Watch What Happens Live! earlier this month.

"I think the more I don't make it mysterious the more people don't care, so yes, we're in a relationship," she told host Andy Cohen at the time.

Chloë also spoke about her Neighbors 2: Sorority Rising co-star Zac Efron and their deleted sex scene in the upcoming comedy. "It was an anti-sex scene because my clothes stayed on the entire scene," she said. "It was pretty raunchy, pretty wild ... I put him in some really compromising positions." 

The film, which also stars Seth Rogen and Rose Byrne, opens in theaters on Friday.
