The former Strikeforce women's featherweight champion tweeted a picture and caption that should certainly catch the attention of the "Rowdy" one:

The timing of the jab is a little strange, considering the Brazilian asked to be released from her UFC contract because she could not make the bantamweight limit of 135 pounds.
The UFC gladly granted her wish and she quickly signed with the all-women's promotion Invicta Fighting Championships, taking on Ediane Gomes in her promotional debut on April 5.
Meanwhile, Rousey, the UFC women's bantamweight champion, is just coming off her first successful title defense at UFC 157 on Saturday, putting away Liz Carmouche with a first-round armbar.
While Carmouche was finished with the same first-round submission that finished all of Rousey's other opponents, she provided a tough test for the champ and nearly locked up a rear-naked choke early in the fight.
The bad blood between Rousey and Santos is well documented, and the fact that they have been the two most dominant women in the sport in recent memory makes a fight seem academic.
However, because neither camp can agree on fighting on bantamweight, featherweight or a 140-pound catch weight, the matchup remains nothing more than a fantasy.
Nevertheless, Cyborg's Twitter post shows that she still has Rousey in her crosshairs, so let's not rule this blockbuster women's fight out just yet.
