Numbers game! Ronda Rousey's mom goes after Cris Cyborg on Twitter

You can't say Cristiane Justino isn't persistent.

The former Strikeforce and current Invicta FC featherweight champion is still on her crusade to get a fight against Ultimate Fighting Championship (UFC) women's bantamweight champion Ronda Rousey. In fact, she was kind enough to give "Rowdy" Lorenzo Fertitta's phone number to get things rolling

Just in case she didn't already have it.

That little comment didn't sit too well with Rousey's mother, Dr. AnnMaria De Mars, who replied back to "Cyborg" with a clever little zing of her own.

@criscyborg @MMARoasted @RondaRousey I'll give you a number - 135

Rousey has repeatedly stated she would welcome a bout against the featherweight champion as long as she drops down to the bantamweight division.

Something Cris tried to do, then quickly aborted.

And despite Invicta president Shannon Knapp's comments that a fight between the two is closer than ever, Rousey is adamant she won't budge on her stance to have it go down at 135 pounds.

The two champions were successful in their recent title defenses, as "Cyborg" knocked out Charmain Tweet in just 46 seconds of the opening round at Inivcta FC 11 on Feb. 27, 2015 in Los Angeles, California. A day later, "Rowdy" one-upped her rival by submitting Cat Zingano at UFC 184 in just 16 seconds (video), also in "The City of Angels."
