Alexa Vega arrives in a super cute dress at the premiere of Underworld: Awakening held at Grauman’s Chinese Theater in Hollywood on Thursday night (January 19).

The 23-year-old actress and husband Sean Covel became pet parents this week — they adopted a sweet new puppy!

“Thank you Shannon at “Bark N’ B*tches” for helping us rescue the most adorable dog! There are many more that need homes. #rescue #adopt” Alexa tweeted before chatting with us on Twitter about the pup’s name.

Alexa added after discussing it with Sean, “Oh no… Now we think her name should be Ramona Flowers. I think we have a winner.”

We love it! How cute is Ramona Flowers?

FYI: Alexa is also pictured at the FX portion of the 2012 Winter TCA Press Tour over the weekend in Pasadena.
