Finneas just wants Billie Eilish to be happier than ever.
Just weeks after the "Bad Guy" singer made her romance with musician Jesse Rutheford red carpet official, her older brother is expressing his support.
"Listen, as long as she's happy," he told E! News at a GQ event for its Men of the Year issue on Nov. 17, "I'm happy."
The "Love Is Pain" singer's comments come two weeks after Billie and The Neighbourhood singer made their red carpet debut at the 11th Annual LACMA Art + Film Gala at Los Angeles County Museum of Art on Nov. 5 wearing matching designer pajamas.
For the event, the "Happier Than Ever" singer wore a crop top and a long skirt with a lace-trimmed slit. She paired the attire with a floor-length robe, platform slides, sheer gloves and an eye-mask on top of her head, that were all monogrammed in Gucci's logo. Jesse perfectly complemented her look by wearing a silky loungewear set, including matching button-up shirt and trousers, completing the look with a pair of Gucci slippers.
The pair added a cozy element to their red carpet looks, wrapping themselves together in an oversized Gucci blanket worn on top.
Jesse and Billie also made their romance Instagram official on Oct. 31, with the Oscar winner sharing a carousel of photos from her Halloween weekend, one of which featured their couples costume. The coordinated look featured a pointed joke at their age difference, with her being dressed up as a baby and Jesse as an elderly man.
Billie captioned the post, "life is craaaaaaaaaaaaaaazy. happy halloween."
Jesse was previously in a relationship with model Devon Lee Carlson for six years until their split last year while Billie dated rapper Brandon Quention Adams for nearly a year before splitting in 2019. She was most recently linked to Matthew Tyler Vorce but announced their breakup in May.
