Just like Serena Williams, UFC Champ Ronda Rousey has been criticized for her body structure in the past.
According to The Daily Mail, more criticisms were thrown at her online bullies on social media just before she took on Brazilian fighter Bethe Correia in Rio de Janiero last Sunday.
"Ronda Rousey is disgustingly manly how can people find her attractive?" one man wrote on Twitter.
"Ronda Rousey is not attractive to me I don't see what some of yall dudes see in her she look straight manly to me," another commented.
While the tennis superstar was defended by JK Rowling last month, the MMA fighter took matters into her own hands.
"Just because my body was developed for a purpose other than f-ng millionaires doesn't mean it's masculine," she said in a documentary video before her latest big fight in Brazil. "I think it's femininely badass as f-, because there's not a single muscle on my body that isn't for a purpose. Because I'm not a do-nothing b-."
The 28-year-old athlete recently made headlines when she defended her bantamweight title from Correia in just 34 seconds.
