Hugh Grant is opening up about his past battle with COVID-19.

During an appearance on "The Late Show with Stephen Colbert," Grant, 60, revealed he battled the novel coronavirus back in February. His wife Anna Aberstein also received a positive diagnosis.

The "Undoing" star told the late-night host that he came down with the usual symptoms that are now commonly associated with the coronavirus such as tightness in his chest and the loss of smell.

He provided rather graphic descriptions of the symptoms as well as some humorous anecdotes about how he reacted to the diagnosis.

"It started as just a very strange syndrome where I kept breaking into a terrible sweat," the British actor told Colbert via People.

He said he also had "like a poncho of sweat."

"Then my eyeballs felt about three sizes too big and this...a feeling as though an enormous man was sitting on my chest, Harvey Weinstein or someone," Grant continued.

He confirmed he also loss his sense of smell, noting that he at first started "to panic."

“I started sniffing flowers, nothing. And you get more and more desperate. I started sniffing in garbage cans. You know, you want to sniff strangers' armpits because you just can't smell anything,” he added.

Grant said he even went home and prayed his wife's Chanel No. 5 perfume "directly" into his face.
