2:09 PM PT -- It appears the woman is OnlyFans model, Monica Corgan, who Kanye's been linked to in the past ... as we reported, the two were spotted at a movie together months ago.
Kanye West has a lot of construction going on at his Malibu home, and it's possible he's now working on a new relationship too ... after being spotted with a mystery woman.
Kanye and the brunette -- who did her best to keep her face hidden from cameras -- hit up Ye's nearly $60 million Malibu beachfront home. Unclear if the woman is just a friend, or something more, but she was decked out in tights, an oversized hoodie and possibly Balenciaga sunglasses.
As we've reported, Kim and Kanye have been on friendly terms as of late -- following her split with Pete Davidson -- but the home Ye bought next to Kim's remains unchanged ... so it doesn't look like he has any plans to actually move in.
