Diddy and his lady love Cassie Ventura are sleeping together -- and want the whole world to know!

The relatively unknown Ventura shared the candid pic cuddling up with her boyfriend, rapper Sean "Diddy" Combs in bed on Wednesday.

Along with the inmate pic, the 27-year-old Forever 21 year old wrote the caption, "@iamdiddy can be pretty heavy sometimes...this picture is cute to me because I normally sleep on top of him...He really fell asleep like this."

We gotta ask though -- if the twosome are both sleeping, who took the photo?!

Even Diddy seems to be open to professing his love publicly. The 43-year-old mogul tweeted photos of Ventura giving him a foot massage and wrote, "@casandrae was talking s*** on IG earlier! But now dis is later. My Baby and she gives mean foot massage. Lol"

Looks like these two are going strong!
