'B**** has lost her mind': Dorothy Wang gets in nasty spat at lavish party with newbie Bianca Espada on Rich Kids Of Beverly Hills

Dorothy Wang isn’t jealous of anyone, especially not Rich Kids Of Beverly Hills newbie Bianca Espada.

The privileged pair got into a fight on Sunday night’s episode during Dorothy’s lavish birthday celebrations in Las Vegas.

Dorothy, a 28-year-old multi millionaire, had flown the whole crew to Sin City on her private plane to party.

Bianca brought her own security guard to the event, then accused Dorothy of being jealous of her.

‘The people that actually are something don’t act like they are,’ said Jonny Drubel imperiously.

‘It’s my birthday, why are you making this about you?’ asked Dorothy, who seemed genuinely bemused by the row that was erupting.

‘I’m with a bunch of haters,’ said Bianca, before storming out in tears.

‘She thinks I’m jealous of her? B**** has lost her mind,’ laughed Dorothy, but she later felt bad and tried to draw Bianca out of her hotel room with a cocktail.

Bianca however refused to open the door.

‘I offered her the olive branch,’ frowned Dorothy who left the drink outside her door.

As the crew argued Brendan Fitzpatrick decided to elope with Morgan Stewart at the chapel down the road.

‘We’re drunk enough, my hair is in a pony, why not just get it done?’ agreed Morgan.

They were at the alter when Brendan called it off.

‘I don’t think this is the place,’ he decided.

‘I was on a cocktail of over-the-counter medication that caused my decision making to be a little bit fuzzy,’ Morgan decided later.

‘I can’t believe we even made it to the chapel,’ she marveled as they nursed their hangovers the next day.

Not the place: Brendan at the last second decided the chapel wasn't the right place to get married

The posse flew out without Bianca who was still offended.

‘Another eventful birthday,’ sighed Dorothy.

Morgan earlier had been furious at Bianca for calling her 150 person wedding a ‘cocktail party’.

‘I’m Mexican and we throw weddings for 600 people and we serve breakfast. To me it’s a little small, but it’s your wedding, your choice,’ shrugged Bianca when Morgan confronted her.

Bianca then called Morgan out for calling Dorothy ‘**** Twinkie’ behind her back.

‘It’s ugly for me to say it…I feel so badly about it,’ Morgan backtracked later of the Asian slur.

Meanwhile, EJ Johnson, the 23-year-old son of basketball great Magic Johnson, had a manicure and gossip with his friends Kyle and Drew in New York City.

EJ named his green nail varnish ‘Jaded’ and discussed options for the line.

The openly gay fashionista then met with some LGBT officials for an art viewing.

They looked at a bathroom mural designed by Keith Haring.

‘This is my kind of artwork,’ he cooed as they admired the phallic drawings.

EJ was so moved by the work of the LGBT support group that he decided to help.

‘I’m going to start by giving the proceeds of the nail polish to the center,’ he said.

Morgan and Brendan saw an astrologist to talk about their pending wedding date.

‘It’s really not an ideal date,’ astrologer Susan Miller told them, advising that they secretly get married ‘a month or two ahead’ to bypass the bad omens connected to May 7.

Morgan then fretted that they both needed to do ‘a cleanse’ and a ‘series of facials’ with lasers.

‘You need to look better than you ever have looked in your life,’ she told Brendan.

Dorothy and Jonny met for dinner, but Dorothy was on her own cleanse.

‘I feel that it is appropriate for Dorothy to go on a cleanse…her face and neck were sharing a room for a while there,’ giggled Morgan.
