Kate Beckinsale shared a peculiar story about her daughter’s boyfriend that caught Jimmy Kimmel off guard.
During her appearance on Jimmy Kimmel’s late-night talk show, the actress shared an unusual and hard-to-believe tale.
On November 25, Beckinsale was on the show promoting her new film, Wildcat, when the conversation steered towards her family.
The 52-year-old shared that the recent years have been challenging due to the loss of both her parents. Her mother Judy Loe passed away from cancer at the age of 78 in July 2025, and her stepfather Roy Battersby died at 87 in January 2024.
In the midst of these tough times, Beckinsale mentioned a peculiar incident involving her 26-year-old daughter Lily Sheen’s boyfriend as a rare ‘bright spot’.
According to the actress, the boyfriend, who remains unnamed, claimed to have laid an egg…

Kimmel, quite puzzled, asked if this was a British expression, which Beckinsale denied, insisting that the boyfriend actually laid two eggs in one week.
She stated: “Well, he said, ‘I’ve laid an egg’ and of course I was like ‘Okay, trying to pull focus away from the cancer operation you know, but it had a shell and a yolk.”
Beckinsale clarified that the egg emerged from his body and not orally.
She went on to elaborate: “He went to the bathroom and then was very surprised to find that he had laid an egg.”
“I got very involved in this, because I really did need a distraction because everything was so horrible,” she added.
Kimmel, still baffled, humorously suggested the actress might have mistaken the egg for one of the boyfriend’s testicles.
When asked if she believed the boyfriend’s story, Beckinsale confirmed, saying he seemed ‘genuinely scared’ when it first occurred.
She further described the egg as a ‘hardboiled one, too, it kind of cooked inside him’, according to her account.
She reflected: “I thought at first, ‘Okay, this is a little bit embellished, obviously he can’t — this doesn’t happen.’ Also, there was a lot going on in my family, so I kind of went, okay, boyfriend’s laid an egg, whatever.”
“And then a week later my daughter was flying back to New York, which is where she — I got a text that says, ‘Oh my God, he’s done it again, and now he’s really freaking out,’ and he’s allergic to tree nuts, so we’ve had some emergencies, but this was more intense than a tree nut emergency.”
Considering that human males typically do not lay eggs, there are limited explanations for this incident.
It could be an elaborate joke by Beckinsale or a prank by the couple during a trying time.
Regardless, it’s a remarkable story.
