Mrs Vardy has been ordered to pay Mrs Rooney this figure, ahead of the full amount owed being decided.
This comes after Rebekah who is married to Leicester City striker Jamie Vardy, lost her High Court battle with Coleen Rooney in 2022, after being accused of leaking Mrs Rooney's private information to the press on social media.
Rebekah Vardy was subsequently ordered to pay 90% of Coleen Rooney's fees, with an initial payment of £800,000.
This order was made after barristers for the pair appeared in court over a dispute over legal costs, with Judge Andrew Gordon-Saker ordering Mrs Vardy to pay an extra £100,000 with 21 days.
"I think there is some scope for a further payment on account so the defendant (Mrs Rooney) is not kept out of her costs, and I think that should be no more than £100,000", he said.
The hearing discussed several preliminary issues, prior to a full "line-by-line" assessment of costs which takes place at a later date, deciding the overall figure which has to be paid. This is expected to take place next year.
"The parties need to get on with this and put it behind them", Judge Gordon-Saker added. "Realistically, it (the line-by-line assessment) is probably going to be next year, hopefully early next year".
At the hearing, Jamie Carpenter KC who represents Rebekah Vardy, said in written submissions that Mrs Rooney's claimed legal bills ran to £1,833,906.89. The written submissions claimed that this figure ran to more than three times her "agreed costs budget of £540,779.07".
Mr Carpenter claimed this bill was "drawn without sufficient care" and had "a 'kitchen sink’ approach", and included "over £120,000 of costs to which Mrs Rooney has no entitlement".
Mrs Rooney's legal representative Robin Dunne stated that Mrs Vardy has shown "deplorable conduct" in the case and that these costs could have been lessened if "she conducted this litigation appropriately".
"It sits ill in Mrs Vardy’s mouth to now claim that Mrs Rooney’s costs, a great deal of which were caused directly by her conduct, are unreasonable", he added.
