Despite her recent ostentatious celebrations in the South of France, it seems that they may have been slightly premature.
Heiress Tamara Ecclestone, 28, was seen emerging from a register office after an official wedding ceremony with new husband Jay Rutland, 31.
Although after her £7million celebrations in France, one could be forgiven for thinking she might be a little partied out.
There were no other guests in sight, suggesting that the couple may have hired the town hall's registry room, which only has room for the bride and groom and two witnesses.
A ceremony at the room costs only £45 with an extra £4 for the marriage certificates - a lot less than the lavish celebrations that the pair threw for 150 guests at the Grand Hotel Saint Jean Cap Ferrat last month, with Tamara's mother Slavica footed the bill.
For that bash, guests included Jason Statham and Rosie Huntington-Whiteley, Sean Connery and Nicola Roberts, while Elton John and Mark Ronson provided the entertainment.
Tamara was seen diving into the French Riviera in her kaftan and bikini after the last ceremony - a feat she was unlikely to reproduce today in the River Thames.
The newlyweds went for low key but smart outfits for the second round of their nuptials.
The bride wore a short cream strappy dress with a ruffled skirt and metallic Christian Louboutin heels, paired with large tortoiseshell sunglasses.
The groom opted for a light grey suit with a matching waistcoat and tie.
Petra and James were a coordinated couple in navy blue, with Petra wearing a short lace dress and skyscraper heels for the ceremony.
Her husband wore a pink tie with his suit, which matched the packs of confetti that Petra held as she walked down the steps ahead of her sister.
