Big Brother Wiki

Michelle Costa was a houseguest on Big Brother 10 (US).

Michelle began the game in a good position, being apart of the early power structure, and having a very close bond with Jessie Godderz. However, after Jessie was blindsided in week four, Michelle became a much larger target especially after winning the next Head of Household competition. After one of Michelle’s last remaining ally, Bryan Ollie, made a deal in the Head of Household competition to keep Michelle safe, it seemed as if Michelle would be safe for the week. However, at the Power of Veto ceremony, Dan Gheesling went back on his deal with Ollie and nominated Michelle as a replacement nominee. Ultimately, Michelle was evicted by a vote of 3-1, placing 7th, and becoming the third member of the jury.

Michelle is an East Coast firecracker who graduated from Cumberland High School and also studied real estate with Remax. She was raised in a large Portuguese family, is currently single and working as a realtor. Michelle has always spoken her mind and was the only person to jump up at her brother's wedding when the priest asked if there were any objections.

She is an avid animal-lover and has a dog named Ralph Lauren, a pair of cats, Tiger and Cookie, a rabbit named Bugsie, a bird and three fishes.

Michelle calls her mother her best friend and feels she can confide in her about almost anything. She's a lot like her father which sometimes causes them to butt heads. She enjoys Portuguese food and seafood, smokes an occasional cigar and likes to listen to hip hop, rap and techno music. She's a sports-lover and likes to watch football, baseball, boxing, basketball and track and field. Her favorite activities are dancing, running, boxing, going to the beach and hanging out with friends.

She describes her ideal romantic partner as tall, tanned, smart, funny and in good shape and wants him to sweep her off of her feet. She describes herself as crazy, funny and outgoing. The political office to which she would aspire is that of President of the United States. Why not go to the top? She is most proud of the trophies and medals she won in running competitions and the marathon she ran in Australia at the age of 15.

Her birth date is December 29, 1979.[1]
