Brenda has dark hair and pale skin. She is fond of cooler colours like green, purple and blue. All colours are on her dresses that she is seen dancing in during "Nicest Kids in Town" and "Miss Baltimore Crabs."
Brenda is also a noticably good dancer. In the beginning of the movie you can see that she is beating Amber in the Miss Hairspray pageant. Her name is later replaced with Tracy's after she leaves.
She has a tendency to flirt with any guy within a two foot radius. Even after it's confirmed she is pregnant, she is seen trying to kiss a boy on the cheek behind Link during "It Takes Two," while Tracy is dancing to "Ladies Choice" she is seen in the background paying attention to a boy close to her, and during "Miss Baltimore Crabs" when Velma says "Girls, go get 'em" you can see Brenda walking away and staring at a boys ass. Seriously Brenda, you got a baby on the way and you're still trying to get some action. Girl you need Jesus.
She's also pretty bad at some sports. In the music number "I Can Hear the Bells," she and other female dancers on the show are seen making a horrible attempt at playing dodgeball. It's kind of adorable actually.
She announces that she is leaving the show for nine months just after Link Larkin sings "It Takes Two." It is presumed that she is pregnant, some believe with Corny Collins' child, because she states that she will be gone for nine months, after being shown arguing with Corny Collins in the background. Her absence opens up a spot on the show that Tracy auditions for and ends up filling.
Fender, a male dancer on the show could possibly be her brother.
It was recently confirmed by the actor who portrayed Brenda in the 2007 film (Cassie Silva,) that Corny Collins is in fact the baby’s father.
If she BREATHES, she’s a THOOOOOOOOOT
