Specialist outlet TMZ reported Monday the pair, who have been dating since 2021, took their relationship to the next level during a cosy Christmas together.
The British actor, 28, went down on one knee “in a very intimate setting in one of Zendaya’s family homes in the United States”, TMZ said.
“We’re told Tom didn’t make a huge show of the engagement – it wasn’t a big, over-the-top proposal – instead, it was very romantic and intimate.
“Our sources say the family wasn’t there… it was just a sweet moment between Tom and Zendaya.”
The pair, who met on the set of Spider-Man: Homecoming, are one of Hollywood’s most beloved couples, despite fiercely guarding their privacy.
Holland was not at the Globes on Sunday – Hollywood’s first major event of the awards season – but Zendaya was there as a nominee for Challengers, a love triangle set in the world of tennis.
But the glitzy ceremony was not without romance: Timothee Chalamet and girlfriend Kylie Jenner set tongues wagging when some of their steamy displays of affection were caught on camera.
