The 'Angels' singer ' who married long-term partner Ayda Field at his Beverly Hills home on Saturday (07.08.10) ' has invited pals to a mystery party at the actress' mother's house next week, with many friends speculating it to be a baby shower after wedding guests were shown the latest addition to his home, a 'room specifically intended to be a nursery'.

A source told The Sun newspaper: 'Ayda's worked on everything from layouts to colour schemes.'

Another added: 't's so strange to have a party so soon after the wedding.'

Meanwhile, further details about the couple's intimate wedding have emerged.

The pair followed up the 30-minute wedding ceremony with a 10-hour reception, though the 40 guests ' including actress Claire Danes and her husband Hugh Dancy - were not served alcohol at the request of Robbie, who has previously battled drug addiction and alcoholism.

A source told the Daily Star newspaper: 'Robbie's battle with the booze is well known so the reception was an alcohol-free zone. It was all very genteel.

'Guests enjoyed cups of tea, perfectly cut sandwiches and of course, lots of cakes.'

A 30ft marquee had been erected in the grounds of the 'You Know Me' singer's mansion, while a 4ft-high flower arrangement spelled out the word 'love'.

The 36-year-old star ' who reportedly proposed to Ayda, 31, with a £160,000 engagement ring while out alien-hunting last month - was overcome with emotion as he gave a speech at the reception.

One guest told the Daily Mirror newspaper: 'His speech was really sweet and no one was expecting Robbie to well up. After that there wasn't a dry eye in the house.

'Robbie said the loveliest things about Ayda and how gorgeous she looked in that gown.'

Best man Jonathan Wilkes poked fun at the couple's love of UFO spotting in his speech, joking he had been 'beamed up' to join them on their big day.

Robbie's Take That bandmates were unable to attend, but sent video messages for the couple.

The pair are now planning a honeymoon in Mexico, before moving on to the English seaside resort of Blackpool for a 'British-style' holiday, to coincide with Robbie switching on the famous illuminations.
