Kim Kardashian shocked her BFF Tracy Romulus by gifting her a $100,000 matte black Tesla Cybertruck for her 45th birthday this week.

The SKIMS founder, 44, shared footage of herself surprising Romulus with the new car on Thursday.

Kim parked the luxury vehicle in the driveway of her $60million Calabasas mansion and told Romulus to ‘turn around.’

Once Romulus spotted the car, which had a large red bow pinned to the hood, she exclaimed: ‘What! Kim are you f***ing serious?! Are you nuts? Are you crazy?’

Kim, who stood nearby laughing and smiling, told Romulus that it was her birthday gift.

‘Shall we take your car tonight,’ Kim asked, before embracing her excited pal in the driveway.

Referring to Kim as her ‘crazy, over the top [best friend],’ Romulus uploaded a blurry image of the Cybertruck to her own Instagram Story.

Over top of video of her and Kim gawking at the Cybertruck in the driveway, Romulus wrote: ‘I literally have no words… @kimkardashian… no one does gift giving like you… this is so over the top crazy… only you… i love you…’

Kim and Tracy looked to be gearing up for a girls’ night out in Los Angeles.

They coordinated for Tracy’s birthday by wearing matching black leather trench coats.

Kim made the rare move of rocking Converse sneakers as she is still recovering from a foot injury.

Along with being among Kim’s closest confidants, Tracy works closely with the billionaire.

According to her LinkedIn, Tracy has been the Executive Vice President, Communications at SKIMS, Kim’s successful shapewear line, since 2017.

Kim’s custom Cybertrucks, one black and one silver, could be seen parked in the background of the Instagram Story clips posted Thursday.

She added her first Cybertruck to her car collection in February 2024, followed by a sleek matte black version in May.

Referring to Kim as her ‘crazy, over the top [best friend]’ Romulus also shared footage of the big surprise to her own Instagram on Thursday

The reality TV star is a longtime Tesla fan and recently introduced fans to her $30,0000 Tesla bot.

She posed for a bizarre Instagram pH๏τo-shoot with the droid, with one image showing her holding hands with it in a Cybertruck.

However, she was forced to deny accusations that she was being ‘paid’ by Tesla founder Elon Musk.

A rep for Kim told The New York Times last month that the SKIMS founder was not financially compensated for the pH๏τos.

Kim’s surprise for Tracy comes amid a heavy promo push for SKIMS’ new winter lingerie line ahead of the holidays.

On Wednesday, Kim shared new sizzling campaign snaps that showed her straddling a fur bench in a skimpy bras and underwear.

The sultry Winter Heat collection includes thong underwear, knit sweaters, bralettes and a plethora of other fashion basics.

Products range in price from $16 for knit socks to $128 for an oversized hoodie.
