Lilly Becker puts on a leggy display as she celebrates her 47th birthday

Boris Becker spent his last birthday at HMP Huntercombe after being convicted of concealing £2.5 million in assets despite declaring himself bankrupt.

But the former Wimbledon champion’s estranged wife, Lilly, celebrated her 47th birthday in a more pleasant venue.

The Dutch model was joined by her boyfriend, sports company owner Thorsten Weck, 50, at George’s private club in Mayfair on Saturday night.

Lilly looked fabulous in a £1,100 checkerboard mini dress designed by royal favorite Emilia Wickstead for the occasion.

She put on a leggy display in the eye-catching ensemble and gave herself a few extra inches in a pair of beige peeptoe heels.

Lilly kept her essentials in a cream handbag while making sure to pull out all the stops for her chic birthday celebrations.

The bombshell shaped her brunette locks over her shoulders into glamorous waves as she smiled for the cameras.

She amped up her striking features with lots of mascara and opted for a touch of shimmery pink lip gloss to pull her look together.

Her dress was designed by Emilia Wickstead, who has also created glamorous ensembles for the likes of Kate Middleton, Princess Beatrice, and Meghan Markle.

Lilly has been dating her boyfriend Thorsten for several months after the pair met through mutual friends.

Lilly’s estranged husband Boris served eight months of a two-and-a-half-year prison sentence before being extradited to Germany in time for Christmas last year.

The tennis prodigy, who won Wimbledon when he was 17 before winning five other Grand Slam titles, is back on TV and the red carpet following his release.

Lilly, who is worth around £4.1 million, was married to Boris for almost ten years from 2009 until they split in 2018.

Former flames: Lilly and Boris (both pictured in October 2017) split in 2018, but last May Lilly said she was still married to Boris and refused to divorce him

But last May, Lilly said she was still married to Boris and refused to divorce him – four years after reports emerged that the couple had split.

She said, “As estranged woman that may be, we are still very much married and have been since we went our separate ways.

“It was intense from the start and a complete, true love story. Everyone who knows us knows that. It’s not that I don’t want a divorce. We have to handle our business at the right time.”

When asked if she still loves Boris, she replied, “Of course I do.”
