Gambling Winnings - Married Filing Separately in California

Hi! We live in California and normally file married jointly, but this year it would most likely benefit us to file separately for a couple of unusual reasons (I did both methods in Turbo tax and filing separately results in a larger refund).  However, before I know for sure, my question is how to treat gambling winnings. All winnings (including W2G's in my name) are mine ... Would I report these winnings as income under my own return or would I split them 50/50 between my return and my wife's? I've read an IRS publication about community property/income but cannot find a specific reference to gambling winnings. Since I live in California, not sure if these winnings are considered community income. Thank you!
