Harry Styles and Zoë Kravitz are said to have recently become engaged after less than a year together, with the actress first seen wearing a reported $1million diamond ring in New York in April.

But Breaking Celebrity News can reveal the seemingly blissfully happy power couple is facing questions over whether their whirlwind romance is genuine or a carefully managed "showmance" to boost both their careers.

Zoë's has repeatedly been filmed in the crowd of Styles' gigs singing along to the 32-year-old's hits, while dancing with concertgoers and watching the former One Direction singer perform from the standing section instead of backstage hospitality areas.

Fan videos also appeared to capture the singer looking toward Zoë during performances.

Attention has also focused on Zoë's interactions with Harry's relatives. Although Harry's mom Anne Twist has not followed the actress on Instagram, fans have recorded the pair embracing, dancing together and standing arm in arm during the opening Wembley show.

Harry's sister, Gemma has been filmed greeting Zoë with a hug.

Another insider told us: "The social media discussion over whether what Harry and Zoë have got is real has taken on a life of its own, but anyone who watched Gemma with Zoë could see there was genuine affection.

"People can read whatever they want into Instagram follows or tales of Harry and Zoë keeping separate bedrooms, yet the reality around them looked relaxed and natural."

The latest speculation follows photographs published last week showing the couple enjoying a picnic on Hampstead Heath during a break from Harry's concerts.

The singer rested his head in Zoë's lap while she stroked his hair, with the intimate images quickly circulating online.

Some commentators nevertheless questioned whether the outing had been staged, while others revived earlier reports claiming Zoë stayed at a London hotel rather than Harry's north London home during a previous visit to the UK capital.

Friends have previously suggested Zoë's has encouraged Harry to embrace a quieter lifestyle centered on fitness, meditation and self-care after she openly discussed her own sobriety.

Despite their contrasting upbringings – Harry in humble Holmes Chapel and Zoë as the daughter of musician Lenny Kravitz and actress Lisa Bonet – supporters believe the pair have found common ground away from the spotlight.
