She stunned fans when she ended her fashion show at New York Fashion Week with a broad grin.
But as she celebrated her success at the event at dinner with husband David last night (Sunday), Victoria Beckham was back to looking sombre.
The 38-year-old designer broke out her trademark pout as the pair were photographed leaving Balthazar restaurant in New York following a celebratory meal.

However, LA Galaxy player David made up for his wife as he beamed at photographers while leaving the eatery.
While Victoria looked chic in a design from her new collection, David looked as dapper as ever in his black trousers and brown jacket with white shirt and brown tie.
David, 37, finished his outfit off with slicked back hair and a pair of thick-rimmed black glasses, giving him a geek chic new look.
Victoria's expression as the pair left the restaurant was in sharp contrast to her wide smile earlier in the day as her Spring/Summer 2013 show at the New York Public Library received a rapturous response from the packed audience.
The Spice Girls star, who previously said she hates the way she looks when she smiles, was seen with her hands over her mouth to conceal her grin as she took a turn on the catwalk following the show.
Following the show, she tweeted: 'Relieved!!! Can't believe it's over. Thank you #vbteam!!! #vbss13 #nyfw X vb.'
After the show, David, Victoria and their daughter Harper were photographed heading to celebrate at Balthazar.

While Victoria wore the same black dress she had worn to debut her collection, one-year-old Harper looked angelic in a white dress, hair bow and black shoes.
Since launching her debut Victoria Beckham collection in September 2008, the former singer's label has gone from strength-to-strength.
Her dresses are regularly worn by the stars on the red carpet and last year, she won Designer Brand Of The Year at British Fashion Awards.

There were also more famous names in the front row than past seasons. As well as Anna Wintour and Mr Beckham, who also attended the last show, Vogue Japan's Anna Dello Russo was present this time (clad in Victoria Beckham, of course).
And tennis player Maria Sharapova wore hot pink trousers to take her seat in prime position next to Ms Wintour.
