Kendra Wilkinson turned 26 yesterday -- but she celebrated it in style the day before with two giant Las Vegas bashes!

First, she kicked off the celebrating poolside Saturday at Caesars Palace Venus Pool Club. Along with husband Hank Baskett, Kendra partied with 16 friends -- including  Playboy Playmate Jessica Hall, Kendra’s assistant/friend Eddie Bochniak, Jon Dorenbos of the Philadelphia Eagles and Pat McAfee of the Indianapolis Colts.

From there, the group grabbed dinner at Social House inside Crystals at CityCenter before heading to Party #2 at PURE Nightclub, where she was spotted dancing with her man before being presented with another huge cake -- this one with three cake-toppers of the sexy star, one of them wearing a "Dancing with the Stars" costume.

FYI -- Kendra is wearing a sparkly dress from La Femme.

While "Girls Next Door" co-star Holly Madison wasn't seen at the party, the two did grab dinner together last night, Kendra tweeting "At my Bday dinner w @hollymadison ! She got me the best gift ever... My red/white/blue costume from DWTS!!! Yayy!!"
