Miley is planning a big raunchy party for her 21st birthday and Liam Hemsworth is reportedly on top of the guest list, reports IBN Live.

The "We Can't Stop" singer has allegedly hired the best party planners for her birthday on November 23, with the star specifically outlining a sex-themed bash.  Sources close to Miley say the Rolling Stone cover girl is reportedly hoping that ex-boyfriend Liam would show up at the party and would give her the ultimate gift, according to Mail Online.

Cyrus and Hemsworth ended their engagement in September, after the "Wrecking Ball" singer's series of infamous performances. Her controversial MTV Video Music Awards stint, wherein she strutted onstage in her underwear and gave a raunchy performance with Robin Thicke, was reportedly the last straw for Liam. Days after the breakup, the actor had been spotted with a new girlfriend.

The ugly episode seems to be all in the past now, as Liam and Miley are reportedly now in good terms. One unnamed source tells Hollywood Life, "Liam and Miley are back in touch. They've forgiven each other and are even talking about meeting up, probably around Thanksgiving. Miley is super excited."

The party is expected to be wild and decadent, with go-go dancers, S&M sex dungeons and cages as major attractions. The birthday bash will mimic bachelorette parties that feature barely dressed whipping boys, creative liquor and cocktails, as well as naughty decorations and surprises. With an army of party planners behind her birthday celebration, Cyrus is set to have an over-the top party to celebrate the day she was born, according to Hollywood Life.

The lewd birthday party will fall on the same day as her American Music Awards performance, giving the "Party in the USA" singer the opportunity to invite the biggest names in the music industry to share her debauchery. The guest list however, remains a secret.  

Cyrus is no stranger to wild birthday parties. Last year, she celebrated with exotic dancers; on Liam's 22nd birthday bash, she posed with a phallic-shaped cake.  Of course, she's just being Miley.

The singer is excited about her 21st birthday, posting a photo of her wearing a tiara and holding a sceptre while out with friends in Amsterdam in an advanced celebration of sorts.
