Blac Chyna: I'll Be On 'KUWTK' ... But It'll Cost Them Big Time

Blac Chyna will make a cameo on "Keeping Up with the Kardashians" ... if the price is right.

Sources close to Chyna tell us she's looking to meet with 'KUWTK' showrunners and negotiate a minor role on the show.

Chyna thinks she knows the value of footage showing the relationship between her and Rob's sisters, but she may be overestimating its worth ... she wants $1 MILLION.

Rob's GF wants even more ... a non-exclusive contract, because she wants her own reality show ... possibly with Rob.

Based on what we know, the chances this will happen are way slimmer than Rob.
