Carmen is a transgender woman who was dating Mac, much to his nervous embarrassment. She later had her Sex-Reassignment Surgery and married Nick and the two had Dee act as the surrogate mother for their baby, who Carmen is actually the biological father of (a donor egg was fertilized with Carmen's sperm; Nick says he is unable to have children).
Carmen is a recurring character, appearing in three seasons. She is performed by Brittany Daniel.
Carmen is a very attractive woman but displayed an obvious bulge in her pants until she had her penis removed. ("Mac Fights Gay Marriage") Mac flirted with her intently before Dennis had to point out her penis to him. From then on, whenever he was with her he was constantly cautious of her waist.
Carmen is first seen flirting with some men in Paddy's. She is open about her status as a trans woman, even when people are ridiculously offensive. Carmen was frustrated Mac was ashamed of their relationship, to the point where his friends thought he was a serial killer because he was acting so strangely. After her surgery, Carmen did not call Mac as he wanted her to and married Nick instead, as he is exponentially more understanding and tolerant.
Mac starts flirting with Carmen at Paddy's, thinking she would be a perfect girl to have sex with Charlie to cheer him up. Dennis points out that she has a penis. Mac approaches her, asks her about it. She owns up to it and starts to compliment his arms. He becomes enamored by her and asks to call her sometime. They hang out many times, to Dennis' disgust, because Mac wants to be first in line when she has her surgery. On one date, she tapped him on his shoulder, surprising him, as a reflex he punched her in the face, some witnesses then threatened him for beating a woman, so he called her a man for having a penis and ran away from witnesses. ("Charlie Has Cancer")
Mac runs into Carmen at the gym, where he finds out she had her penis removed. She introduces him to her fiance, Nick. Mac becomes upset that she did not call him after having her operation and decides to fight gay marriage in order to break them up. His efforts do not work. ("Mac Fights Gay Marriage")
After Dee gives birth, she reveals that she'd been impregnated by Carmen's sperm, and had acted as a surrogate mother for Carmen and Nick. She immediately gives her baby to the happy couple. ("Dee Gives Birth")
