Lisa Vanderpump teased on Twitter she was planning something big for daughter Pandora's birthday.

And the 55-year-old reality star wasn't kidding - revealing exclusively to DailyMail.com that she gifted her daughter and husband Jason Sabo with the down payment on a fully-furnished home for her birthday on Saturday.

An overcome Pandora said she burst into tears once she realized the beautiful Los Angeles home - which her parents had painstakingly decorated exactly to her taste - was hers.

Surprise! Lisa Vanderpump and husband Ken surprised daughter Pandora with a down payment on a fully-decorated new home for her and husband Jason for her 30th birthday

Pandora said she thought she was just going to a dinner party at the address and had no idea what her mom had in store.

'I cannot believe as I walked in - thinking I was going to dinner - that my mother had poured her heart and soul into the most perfect house I’ve ever seen,' she told DailyMail.com.

Pandora said it was a 'completely overwhelming surprise' and admitted she 'cried profusely' when she saw the stunning home.

She added: 'I could tell that every little display, piece of furniture and layout was designed with me in mind.'

Gorgeous: Pandora said she broke down in tears of joy when she realized the lengths her parents had gone to to decorate the home to her exact taste, with father Ken picking out the piano she'd always wanted

Pandora also said that it finally made sense why her parents had asked her 'a myriad of questions over the last few months'.

She told DailyMail.com that they would grill her on things such as 'what kind of couch would you have if you owned a house?' and 'what kind of kitchen would you like?'

'The attention to detail and reflection of my taste is utter perfection and the fact that she did this all by herself in so little time is astounding,' added Pandora.

The light-filled home features a large open planning living and dining area, a large outdoor entertaining area with a pool and an enclosed lawn and courtyard.

A pink bow on the front door greeted guests, and there were pretty floral arrangements throughout.

Vanderpump Wine & Spirits founder Pandora praised her mom as 'a force of nature and the most giving, generous, unbelievably hardworking person I know.'

'My father’s touches on the house too were the sweetest present I could dream of (like a much longed for piano!) and the fact that my parents dedicated so much time and effort to this for me makes me feel like the luckiest girl in the world.

'They’ve helped Jason and I start our dream life in our dream home and we cannot wait to live in it!' said Pandora.

London-born Lisa told DailyMail,com it was a dream come true to be able to give Pandora and Jason a helping hand.

And the animal rights activist said the gift was partially a thank you for Pandora's help planning Lisa's upcoming World Dog Day.

'It’s a parent’s dream to be able to give their kids a leg up in this world,' said Lisa. 'Especially when your kids are hard working, altruistic and good-hearted.

'They’ve been working diligently on their business, LVP Sangria, and supporting our Vanderpump Dog Foundation and many charities.'

'Pandora has been so helpful in setting up our World Dog Day on May 22nd and also launching her Charity Market, so for me to organize this for them was a pleasure.'

But the straight-talking reality star pointed out that the gift was a down payment and that the mortgage is now Pandora and Jason's responsibility.

'This was a gift to both of them to celebrate 5 years of marriage and both of their 30th birthdays,' said Lisa.

'But they do now have a mortgage, so this is a gift that definitely comes with responsibilities!'

The generous gift comes as Lisa has been open about her desire for grandchildren. On an episode of RHOBH last year, the restaurateur even showed off a cute onesie she'd purchased five years earlier in preparation, and said she couldn't wait to spoil her future grandkids.

Lisa teased her big surprise for Pandora on Twitter earlier on Saturday.

'30 years ago today I was on my back with my legs in the air, still reaping the benefit lol' she wrote on Twitter. 'Happy birthday you wonderful creature.'

Earlier, she teased: 'Ahh this week I feel I created the biggest surprise ever! A happy birthday to @PandoraVT.

'Kindest person ever today mummy pulled it off,' she wrote, adding a crying laughter emoji and a heart.

In addition to planning her big birthday surprise, Lisa has been hard at work preparing for her Vanderpump Dog Foundation's World Dog Day, which takes place in Los Angeles on May 22.

The event will feature fun activities for dogs as well as appearances by the cast of her Bravo show Vanderpump Rules and singer Lance Bass.

The reality star and dog lover also campaigns against the practice of eating dog meat in China with her Stop Youlin Forever organization.
