You think Lindsay Lohan parties now? Wait until she turns 21.
"I'm going to milk it because it's a big birthday," Lohan, who plans to mark the July milestone with a bash in – where else? – Las Vegas, says on Wednesday's The Ellen DeGeneres Show
Lohan, who said recently she continues to hit the clubs even after rehab because she's lonely
, also tells DeGeneres that she plans to gamble for the first time while in Sin City.
"I'll go and learn," she says.
DeGeneres, placed on bed rest
after hurting her back over the weekend, again hosted her show from an adjustable hospital bed. Next to her, Lohan reclined on a bed set up for guests.
Lohan, whose film Georgia Rule
opens this month, notes that her birthday celebration may also have a quieter aspect.
"I'm to have a dinner in Malibu," she says. "I'm going to be with my family and friends."
