Vanessa Hudgens seemed to be having a blast as she helped her younger sister Stella Hudgens ring in her 18th birthday with a big bash at Beacher's Madhouse on Saturday in Hollywood.

According to Just Jared Jr, on November 16th the birthday girl was joined by a few friends that included Disney star Bella Thorne and her boyfriend Tristan Klier, Sammi Hanratty along with the sisters' mom Gina Hudgens.

A source told the Daily Mail, "Vanessa and Stella were dressed in similar beaded and fringed outfits and danced the night away with friends including Willow Smith, Bella Thorne, Kyle Massey and Tristan Klier."

The "Spring Breakers" starlet seemed to be enjoying her sister's milestone birth even though her boyfriend Austin Butler was noticeably absent from the celebration.

Vanessa Hudgens chose to wear a long green skirt and halter top in order to flaunt her flat stomach to her sister's Bollywood themed birthday party. To accessorize the look she wore a detailed headpiece along with plenty of bangles and other body jewelry.

Meanwhile, Stella Hudgens opted to wear a short black skirt and embellished bra for her birthday. Following the festivities the 18-year-old tweeted, "so much fun celebrating my bday @beachersmadhouse thank you @jeffbeacher for the perfect party #beachersmadhouse."

Vanessa took to her Tumblr page to give her little sister a born day shout out. She wrote, "HAPPY BIRTHDAY to my favorite person in the world, @stellahudgens. I love your face off so much it's not even funny. I can't believe you're 18!!!!!!!! #woman #biggirlnow #fox #sistasista."

Just Jared Jr reported that the Bollywood themed bash was decorated with a purple, red and gold colored candy station from the Sugar Factory, food from 90210-Pho, a henna artist and performances by The Pawn Shop, Amazon Ashley, Mini Kanye West and Mini Prince.

There was also a Bollywood themed birthday cake from Cake Studio LA.
