"If one of us had to be responsible for actually calculating that I don't think it would ever happen," said Lisa Lovett, 31, a college career services worker in Denver.
Among Lovett's current picks: Beyonce, Jay-Z, Justin Bieber, Prince Harry and Suri Cruise. Her team's running fourth, but the season isn't over until the end of July.
Each team owner in Lovett's league antes up $10. Winner takes all, or about $90 once the $20 fee to the site is paid.
In a different league but using the same site, Smith's team includes Bieber, Jason Segel (in a new movie, dating Michelle Williams), Kardashian ex Kris Humphries and Mason Disick, the first offspring of Kourtney Kardashian who just became a big brother — in season!
"The knowledge people display is amazing," Smith said of her fellow team owners. "People do their homework. No one wants to be last."
Drafting celebs is tricky on Riley's site. Celeb goes to rehab? Deduct 10 points. Arrests are minus 5 and mug shots minus two.
Engagement and pregnancy announcements, on the other hand, are worth an extra three points. Add five for marriage, birth and adoption news.
Riley bases play on People, Us Weekly and InTouch. Covers are the biggest scorers at 10 points. Disses mean deducted points — three off for losers in Us Weekly's Who Wore it Best section, for instance, and three off for losers of Style Showdown in InTouch.
Strategy is equal parts radar, research and luck.
"Whenever 'The Bachelor' is on, if you can figure out who might be the pick, you're golden," Riley said. Same goes for "The Bachelorette."
TV's Teen Moms, Housewives and American Idols (aspiring or anointed) are usually everywhere, along with the entire Kardashian family. Awards season is awash in nominees, who are always a good bet, and movie promotional tours and premieres are key — hello Robert Pattinson and Kristen Stewart with three movies between them to hawk.
