Drake‘s highly coveted Hidden Hills estate is seeing huge interest after being put on the market Monday … and it’s drawing big celeb eyes, namely Britney Spears!

Witnesses on the property tell TMZ, the YOLO Estate was flooded with potential buyers on Tuesday — holding showings for 20-30 guests — and within that group was Brittney Spears and her fiancé Sam Asghari.

It’s unclear what drew Britney to the property, aside from it being one of a kind. The home does have a great recording studio … maybe a sign of things to come from the pop icon?

We’re told Britney was looking at the package deal — the estate and the two neighboring properties — creating the ultimate compound offered at $22.2M! She’s certainly got the cash, being worth a reported $60M … and she’s got a house to sell that’s worth a few million.

We’re also told Caitlyn Jenner toured the estate Tuesday as well … safe to say Drizzy caught everyone’s attention!

As we reported, Drake listed the 3 homes on Monday … The main mansion — coming in at 12,500 square feet — has an asking price of $14.8M and features a private theater, swimming pool with a bar and waterfalls, and tennis courts.

Drake won’t have a problem selling his estate … we’re told the house already has a handful of serious buyers … with expectations that there will be several offers by week’s end.
