The newlyweds were seen at a drive-thru McDonald's in Los Angeles.
But as they couple waited for their food it appeared that the mood soured and they were seen looking straight ahead with sad looks on their faces in pictures obtained by The Sun.
It appears Bianca had a hankering for ice cream as she licked a soft serve cone while Kanye drove their $100,000 black Land Rover Defender.
It's unclear what the pair were talking about but it's recently been suggested that Bianca is "not really about being famous" and has "struggled" with being in the spotlight, unlike his ex Kim Kardashian.
The 45-year-old rapper tied the knot with the Yeezy architect, 28, in a private ceremony earlier this year and they've been snapped in public enjoying a number of dates.
However, one source has claimed Bianca is "a lot more low-key" than Kanye's other exes, including Kim and model Julia Fox.
She has also reportedly been finding it tough to see so much paparazzi around and "doesn't want to be giving interviews".
"Bianca doesn't hang too much with her own crowd, she's all about Kanye and mostly with him 24/7, but dating Kanye really can be a full-time job.
"Bianca has known Ye a long time, she has a lot of patience, she knows how to handle him, and is happy for him to be in the forefront," the source said.
Unlike Bianca, reality star Kim had her own business empire while dating Kanye and "couldn't always drop everything" to be by his side.
"It is also no secret she likes to sometimes set up pap photos and play the game, but Bianca isn't hugely into all that, she's very chill and just wants to focus on their business," the source added.
Bianca joined Kanye's Yeezy company in November 2020 after getting a Masters degree in building design at Melbourne University in Australia.
She set up her own jewellery brand called Nylon's Jewellery during her time as a student.
Speaking to The Sun, the source said Bianca and Kanye "work" because she agrees with what the rapper asks of her.
They also said she is more than happy for him to style her "in whatever bizarre outfits he wants".
Bianca underwent a drastic makeover after marrying Kanye, legally known as Ye, as she ditched her long brunette locks for a platinum blonde pixie cut.
She has also started wearing a lot more avant-garde outfits and tends to stick to more neutral tones.
