It was a celebration of months of hard promotional work that has seen Miley Cyrus in various states of undress.

And the singer clearly wanted to let off some steam at the launch party of her new album Bangerz in New York on Tuesday night.

The former Hannah Montana star reportedly flirted with various people at the bash, while her mother Tish was also in attendance.

UsWeekly report that Miley arrived fashionably late to her own party at around 12:45am.

DJ Sinatra was in charge of the music in the adjoining Jazz Room inside The General, on Manhattan’s Lower East Side.

An eyewitness told the publication that Miley ‘playfully grabbed a blonde female friend’s breasts’ and later ‘motor-boated [Beachers’ Madhouse performer] Amazon Ashley’.

The star at one point was also said to be ‘all over’ the rapper Mike Will Made It – and danced to his song 23.

Another observer told UsWeekly that Miley was ‘grinding all over him, kissing his neck’.

Hilariously, the report claims that Miley was unimpressed when the DJ played one of her earlier more pop-orientated hits Party In The USA.

At one point Miley was said to have ‘made out with her unidentified blonde female friend’ before ditching her and rapper Mike for a ‘handsome mystery man wearing a grey suit’.

But she reportedly left alone just before 5am.

The We Can’t Stop singer held a bejeweled handbag as she was escorted out of the club to her vehicle by a friend.

Earlier in the day, Miley wore a sparkly silver chain necklace and ripped white jeans that hung well below her waist, revealing her white mesh panties.

Miley was true to form, flashing her tongue for the cameras as she held out her CD.

Miley certainly has a lot riding on the success of her latest album.

The star is desperate to break away from her teen image and be considered as an artist.

However, Miley’s chosen route so far has been to shock as much as possible with her image, rather than her music.

Miley explained in her MTV documentary The Movement however that her latest sound is ‘not’ a transition.

She revealed: ‘People always like to call it a transition. I’m the same human – I have the same heart that I had five years ago. Everything about me is the same. Same skin, same human.’

She also explained: ‘With this record there’s a lot of pressure, because I haven’t had one out in two years’.

According RadarOnline, Miley wanted no expense spared in making her launch night one to remember and flew in monkeys, little people and the cast of Beacher’s Madhouse.

‘Miley wanted the most over the top ‘Madhouse’ ever so she had Jeff bring the cast from Los Angeles including monkeys and little people,’ a source told the website.

Aiming for an outrageous party with lots of surprises, ‘Miley isn’t doing anything small scale anymore, everything is a huge dramatic production.’

Earlier in the day, Miley put on quite a show at Times Square, giving fans the explicit and raunchy performances they’ve come to expect.

She sang her latest single Wrecking Ball in a pair of extremely short shorts.

Most of the dance routine involved a lot of grinding, all in a day’s twerk for Miley.

But she kept her top half covered with a large white shirt, perhaps giving her fans something to look forward to at the release party.

In an accompanying interview with the Today Show anchor, Miley revealed that she’ll continue her ‘sexual’ performances to at least 40 years of age.

‘Probably around 40, I heard that’s when people don’t have sex any more. So I guess maybe around then,’ the star said when asked by Matt.

The We Can’t Stop singer also remained defiant about her antics of late – which include her steamy MTV performance and a clash with Irish singer Sinead O’Connor via social media – insisting she won’t apologize for her behavior.

Miley quipped: ‘If I owe anybody an apology it’s the people who make the bottom half of shirts.’
