Internet pioneer Martha Lane Fox was left red-faced after tweeting details of her appointment to the House of Lords.
The lastminute.com co-founder accidentally broke protocol by announcing she would take the title of Baroness Lane-Fox of Soho.
David Cameron's digital guru, who has been appointed to sit on the non-political cross benches, promised to get a "robe on and get them moving"
And she then complained that light-hearted tweets to friends about her appointment had been published.
In one - subsequently removed - she joked to a Labour councillor in neighbouring Camden who said the choice of London's nightlife hotspot Soho made it a "cool title".
"Get free cocktails and nipple tassles right?" she posted.
The entrepreneur, who will become the youngest female peer at 40, also founded the Go On UK charity that aims to spread digital skills and has her own grant giving foundation, Antigone, funding charities that target neglected causes.
She is a non-executive director of the Efficiency and Reform Board at the Cabinet Office and the Government Digital Service.
