Romeo -- Yo, Kardashians ... Let Me Get a Cup o' Sugar!

Romeo Miller can hit up Khloe Kardashian for a hedge trimmer or Tyga for a ladder ... because he just snagged an off-the-chain rental in their celeb-packed gated Calabasas community, The Oaks.

Miller recently got the keys to a palatial 8,991 sq ft home with 6 beds/8 baths in the same 'hood where Khloe & Kourtney Kardashian, Katie Holmes, Tyga and Kylie Jenner lay their heads each night.

Master P should be proud -- his son's crib sits on nearly one acre, and comes fully loaded with a rock pool spa, waterfalls, and a BBQ center ... all for $29,686 per month!

Most of all, Romeo's smokin' hot GF Toneata Morgan 's gotta love the place.

Important footnote: Kylie's head goes on her own pillow, NOT Tyga's ... at least for the next 3 months.
