The 39-year-old actor sent the rumour mill into overdrive when he was spotted wearing a silver band on his wedding ring finger in a photo he posted on Twitter in July.

Zachary has been dating model Miles for around two years - with the pair confirming their relationship on social media in August 2014 - so fans were only too eager to know if they'd made their commitment official.

Now the 'Star Trek Beyond' star has put an end to the speculation insisting he is not engaged but that he and Miles are definitely committed to one another so it wedding bells could be ringing in the future.

When asked if he was engaged, or indeed married, he told E! News: "I'm just wearing a ring, man. It's the only finger this ring fits on. I like to keep them (fans) guessing. I don't know, we'll see what happens."

The photo which sparked the engagement rumours was in fact a sponsored advert for Amazon Prime.

The loved-up pair recently showed their affection for each other on social media - just last month the Star Trek Beyond actor posted a paparazzi photo on Instagram of himself and Miles, 27, walking hand-in-hand whilst walking their dogs Noah and Skunk in New York City on his 39th birthday.

The caption read: "i never post paparazzi pics - but this one captures the joy of the amazing birthday morning family walk which lead to an incredible day full of gratitude and creativity and love." (sic)

Zachary stars as Commander Spock in 'Star Trek Beyond' film, his third appearance as the half-human, half-Vulcan Enterprise crew member.
