In 2007, she earned $700,782.50, her largest career payday at that time, during the World Championship of Online Poker NL Hold'em Main Event with a second-place finish in the 2998-entrant field. She had originally placed third in the event, but the winner was found to have violated the Pokerstars terms of service, which caused a disqualification ruling and caused all contestants to be elevated one place in the rankings. The tournament is run online by Rousso's sponsor, PokerStars, and she had originally earned the third place prize of $463,940.50. At 2008 World Series of Poker she again had three in the money finishes. She placed 57 of 605 in Event 38, $2000 Pot Limit Hold'em, placed 44 of 2693 in Event 52, $1500 No-Limit Hold'em, and 625 of 6844 in the Main event 54, $10,000 No-Limit Hold'em.
