Are these two finally back together?

Who knows -- they'll always have a tempestuous, tumultuous relationship -- but last night, Blac Chyna and Rob Kardashian reunited for date night, sharing dinner out at Tao in Los Angeles.

The off-again, on-again couple appeared happy and healthy -- Rob seems to have dropped some weight -- Chyna in new purple-dyed locks, white leggings and a denim jacket and Rob in black jeans, and an olive green hoodie and cap.

The couple broke up in February for a second time after the birth of their baby daughter Dream in November. Rob had proposed back in April. The couple has posted various make-ups (and make-outs) on social media, so it's always confusing as to whether to two are on or off -- or whether their breakups and make-ups are staged for their reality show Rob And Chyna or the real deal.

Keep watching, we're going to try to keep up with these Kardashians and tell you if this make-up is for real!
