You know what's cooler than a million dollars? A billion dollars baby girl! 

Internet entrepreneur Sean Parker  who was portrayed by Justin Timberlake in the 2010 Oscar-winning film The Social Network  has welcomed a baby girl with fiancee Alexandra Lenas, according to Us Weekly.

The baby's name is Winter Victoria Parker. Sean proposed to Alexandra in February 2011, and the couple plans to marry later this year.

Sean, who is 33, co-founded the music-sharing site Napster in the '90s, and he was the first president of Facebook, although he is no longer with either company. More recently, he is a backer of the music site Spotify.

Sean's net worth is estimated at a not-too-shabby $2.1 billion. In other words, they'll be able to afford all of the rattles and diapers that they need  and then some.
