Real Housewives Of Beverly Hills: Teddi Mellencamp makes debut while others anxiously await Lisa Rinna

The Real Housewives Of Beverly Hills kicked off season eight on Tuesday with a champagne soaked trip to Las Vegas.

Teddi Mellencamp Arroyave, the 36-year-old daughter of John Cougar Mellencamp, made her debut as a regular cast member.

She was thrown into the fray with original RHOB cast member Camille Grammer who was back as a guest on the series.

The cast of last season was back with the exception of Eileen Davidson who did not return for season eight of the Bravo show. 

It was the third straight season in which all the RHOBH stars are married. 

Everyone was apprehensive about reuniting with Lisa Rinna, who had caused a stir last year by suggesting Dorit Kemsley was a cocaine user and calling Kyle Richards 'an enabler' to her sister's alcoholism.

'It's a recipe for disaster,' noted 57-year-old Lisa Vanderpump as the party got underway.

Trouble? Last season Harry's wife Rinna had called Kyle and 'enabler' to her sister Kim's alcoholism. The show ended with the awkward entrance of Rinna leaving a cliffhanger for next week's episode on Bravo

The season premiere titled Stronger Than Ever opened with Erika Girardi creating a new ballad called Missing Piece.

'I'm going to maximize my motherf***ing time,' announced the 46-year-old pop singer, whose husband is top trial lawyer Thomas Girardi, 78.

'I'm here today because of the support of my husband,' she admitted.

The diamond-clad  singer later showed Kyle her 'office' that included some super bright vanity lights and a podium with multiple mirrors for dressing.

'If you look good in here you look good anywhere,' said Erika proudly.

She discussed her time on Dancing With The Stars.

'I was like a fish out of water,' she admitted.

Meanwhile, Lisa Rinna ordered a vitamin drip for herself and her daughters who are both budding models.

'I'm a momager…I hustle, I work hard…I am in charge of everything,' she said, noting that her husband has been less than helpful.

'God love Harry Hamlin, but he's not doing s***,' she huffed.

They also took cortisone shots for pimples as Lisa claimed that she wanted to keep her daughters grounded.

Kyle then met with Lisa Vanderpump to chat about Kyle's new show American Woman, which is inspired by her life with her mother in the 1970s.

'It's definitely real life, with fiction,' said Kyle vaguely.

Dorit was hanging out with her son Jagger, who had just started talking properly.

They met Teddi and her husband Edwin, plus their kids, for some musical playtime.

Dorit asked Jagger if he was excited to make some new friends and he sweetly replied, 'I don’t know which friends and their names.' 

Teddi grew up in Hilton Head, South Carolina where 'you can't get a house for less than a million dollars'.

'But I knew the value of a dollar, always,' she added.

The horse rider admitted that she met her husband on a 'one night stand'.

'I thought his name was Edward, his name is Edwin,' she laughed.

On her famous father, Teddi said was 'never handed anything on a silver platter'.

'I thought everybody's dad was on the radio,' she said, noting that as a kid she was more interested in My Little Pony than her father's music career.

Dorit and her husband Paul 'PK' Kemsley chatted about the pending Vegas trip.

'Last time I saw Erika she was really horrible to me, I've listened to Rinna call me a pervert, staring up their dresses all the time,' grumbled PK, who is Boy George's manager.

'Rinna was just a joke, horrible,' he added.

At the airport Dorit dropped a bombshell about Teddi.

She revealed that Harry told her that her sister Kim 'could not be around the group anymore', ever.

'It was just weird…I can think of so many things I'd rather do than talk to Lisa Rinna about Harry Hamlin. Pap smear, root canal, enema,' she mused.

The show ended with the awkward entrance of Lisa Rinna leaving a cliffhanger for next week's episode on Bravo.
