Roman Abramovich's daughter Anna sparks engagement rumors as she flashes a giant diamond on her ring finger while shopping at Harrods

After high-profile romances in her teens, Anna Abramovich has kept her love life out of the spotlight in recent years.

Still, it looks like Anna has a new mystery man in store as she was spotted wearing a dazzling ring on her engagement finger on Tuesday.

The 32-year-old daughter of Russian oligarch Roman Abramovich proudly showed off a large diamond while shopping in London's Harrods on Monday.

Anna kept the rest of her look low-key for the outing, pairing a navy sweater with wide-leg jeans and white sneakers.

Beside her stood a male companion, dutifully carrying her shopping bags.

Anna has been quiet about her love life since she was linked to lothario Calum Best in 2012.

She was 19 at the time, 12 years younger than Calum, but the couple's tail was wagging when they were spotted on holiday together in Sardinia.

A source told Grazia at the time: 'Calum is really angry with her but she is understandably keeping her guard up as she is all too aware of his playboy reputation. But there is definitely chemistry there.'

Calum's rep told MailOnline that the pair had been 'friends for years and she went with him to Sardinia to watch him film for Sky Sports Italia', while a source close to Anna's father Roman described the rumored romance as 'completely false' .

Before Anna was linked to Calum, she was engaged to Moscow-born lawyer Nikolai Lazarev.

She was only 18 years old at the time, while Nikolai, at 27, was almost ten years older.

The couple lived together at the time in an expensive place overlooking London's Hyde Park, but they separated before tying the knot.

A few years later, she made the move to focus on her education, moving across the Atlantic to New York City, where Anna studied philosophy at Columbia University and graduated in 2018.

In 2014, the New York Post reported that she had been spotted house hunting in Manhattan with her mother, looking at a $47.5 million (£62.2 million) penthouse apartment in Walker Tower.

However, it is believed that she has moved permanently to London in recent years and is said to be studying at Le Cordon Bleu cooking school in London.

Roman's daughter Anna is one of five children the Chelsea owner had with his second wife, Irina Malandina, a London-based former Aeroflot flight attendant who married the Russian tycoon in 1991. They divorced in 2007.

Like her younger siblings, Anna is used to living large and would be eligible for an inheritance of $3.15 billion (£2.4 billion).

Although little is known about her upbringing, she reportedly attended school in London by helicopter and driver.

At the age of 16, her birthday party made headlines, reportedly costing hundreds of thousands of dollars.

According to the Times, the invitations for each of the guests – reportedly 500 schoolchildren – included silver cards with the birthday girl's initials embossed.

They also received an expensive gift before the event and were only allowed in if they wore it: girls received silver and crystal charm bracelets, while boys received black leather straps with beads designed by Anna herself.

Teenager Anna wore an orange Dior couture dress to the party at a nightclub in London's West End, where Alexa Chung played and the Klaxons performed.

Non-alcoholic cocktails, marshmallows, chocolate dipped strawberries, cakes and other desserts were on offer, while there was a photo staging with props and even make-up artists.

The party continued until 3am, with the guest of honor spending most of the event in a VIP lounge with her closeted friends.

“I'll never forget that party,” said one guest. 'I wear my bracelet every day so that when people ask, I can say I went to Anna's party. Virtually every teenager in West London and beyond knows about it.'
