Alexa Starr is a pre-made playable adult Sim from The Sims Life Stories. She first appears in Vincent's story when Vincent receives a call from her after seeing him on his e-Dating profile and that she'd like to meet him at Don Calamari's for a date. Vincent decides to go and he meets her there.
After drinking coffee he heads to the bathroom. Meanwhile, Vincent's ex-girlfriend Samantha Hayden sneaks into the kitchen and sabotages the food. Alexa and Vincent decide to order a meal, but while eating it Alexa falls asleep in her food. After she wakes up, Alexa is embarrassed by the whole situation and she decides to leave the restaurant.
She is later invited over to Vincent's house, along with Naomi Hunt and Greg Chomsky, the latter of which requested that Vincent invite her over, since Greg had taken a fancy to her. Alexa becomes playable at the end of Vincent's story. She tends to interrupt during conversations and has an addiction to coffee. Alexa also vibrates, most likely because she drinks coffee on a regular basis.
It is possible that she might be related to Emmy Starr, as they share the same last name. However there is no evidence to prove that this is the case. When the household is first played, Alexa is 29 days from being an elder. She has the Romance aspiration and the Sagittarius zodiac sign. Even though the story-line implies that Alexa is starting to develop a relationship with Greg, they are usually marked as "Just Met" when either of them are first played.
