When she falls asleep, we know where she goes.

Billie Eilish once broke up with a boyfriend after having a dream about actor Christian Bale.

“A couple years ago I had a dream about Christian Bale and it was like in a little cafe in the sunlight, and it made me realize that I had to break up with my boyfriend,” she divulged during an interview Friday at an Oscars nominee luncheon.

Her brother, Finneas, who was also in the interview, began laughing at the anecdote, which encouraged the 22-year-old “Bad Guy” singer to double down.

“Genuinely,” she continued. “I woke up and I came to my senses.”

Eilish — whose song, “What Was I Made For?,” from the “Barbie” soundtrack is nominated for an Oscar — did not reveal the identity of who she dumped, but she was last romantically linked to The Neighbourhood’s singer Jesse Rutherford.

They dated for about seven months before going their separate ways in May 2023.

Their split came as a shock, considering Eilish was comfortable publicly praising her beau as she filmed a video for Vanity Fair in November 2022.

“I’m really excited and really happy about [our relationship],” she smiled at the time. “I managed to get my way to a point in my life where I not only was known by a person that I thought was the hottest f–king f–ker alive, but pulled his ass.”

Before dating Rutherford, the nine-time Grammy winner dated actor and writer Matthew Tyler Vorce.

They were first spotted showing off some PDA while grabbing coffee in Santa Barbara, Calif., in April 2021.

The pair broke up by May 2022, with Vorce coming forward to deny cheating allegations.

“Nobody cheated on anyone,” he wrote on his Instagram Story at the time. “Relationships end. Simple as that. Creating rumors and LYING on the internet is dangerous.”
