She had just enjoyed what was surely a pleasant evening of revellry.

So no wonder birthday girl Brandi Glanville looked slightly the worse for wear as she put on an amorous display with her megarich new beau outside a trendy restaurant in Los Angeles on Wednesday.

The Real Housewives Of Beverly Hills favourite appeared to be having a great time as she locked lips with Donald 'DJ' Friese, who is named after his glazing supplies billionaire father.

Hitting the jackpot: Brandi Glanville put on an amorous display with her megarich new lover in West Hollywood on Wednesday

Brandi, who turned 44, was looking good for her age in a barely there off-the-shoulder black dress that showcased her toned thighs and honed upper arms.

The saucy former model, who had just enjoyed a meal at the trendy Nice Guy eatery, rounded off her stylistic mode with a towering pair of golden stilettos and a garish leopard print purse.

Her look certainly seemed to have impressed Donald, as not only did he stop her so he could give her a kiss in public, but he was also carrying an expensive-looking box full of roses.

The gift doubtlessly won her over, as she later posted an image the flowers on Instagram and said: '@djfriese thank you for the best night EVER❤️I'm officially in the "L" word.'

Too much Brandi? The reality television beauty looked a little worse for wear after their meal

Given he was holding a box of roses, it seemed incongruous Donald had dressed up like the Milk Tray Man in a black shirt, trousers and leather shoes.

After their amorous display cheeky Brandi also shared a photo of herself sprawled on a double bed for her fans to ogle at, which she captioned: 'Yep this happened was such a magical night thank you @djfriese.'

Her new man is in line to inherit a huge slice of his billionaire father's fortune, and in some ways is an upgrade on her ex-husband, Sunset Beach legend Eddie Cibrian, who dumped her after starting an affair with his current wife LeAnn Rimes.

Donald Sr made waves after he sold his business C.R. Laurence for an eye-watering $885 million after taxes, then handed over $85 million to his employees.

Joking about his humble beginnings when he made the deal last year, the 76-year-old said: 'You know the saying, 'Some people are born with a silver spoon'? I didn't even have a spoon.'

He was the company's sixth employee after moving to Los Angeles from his native Pennsylvania. When Donald arrived he had just $125 in his pocket, and ended up taking over the company.

He cashed out after accepting an offer of $1.2 billion in cash and $100 million in promissory notes for the business.

Donald Jr, who likes to be addressed as DJ, is an executive vice president at the company, while his father serves as chairman and CEO.

One person it looks like will not be accompanying Brandi on double dates in the future is her old co-star Lisa Vanderpump.

The 56-year-old restaurateur answered a viewer's question on Watch What Happens Live about whether or not she talks to the blonde, who was absent from the show's seventh season.

She revealed that her relationship with Brandi is non-existent and that she 'got to know the block button' with her.
