Amal Clooney's family want to show George Clooney he is a ''much-loved and cherished'' part of their family.

The British human rights lawyer and the 'Monuments Men' star - who tied the knot in Venice, Italy last month - will be the guests of honour at an extravagant post-wedding party, hosted by her parents, Baria and Ramzi Alamuddin, at the Danesfield House Hotel & Spa in Buckinghamshire, England on Saturday night (25.10.14).

A source told E! News: ''[Amal's sister] Tala wanted to help her parents plan the party at Danesfield House and they all are eager to make this weekend one to remember for George and Amal as a thank you for the amazing time they all had in Venice. The feeling within the Alamuddin family is still very much one of celebration and joy about the wedding.

''They're keen to show George how pleased they are that he and Amal are so happy together and that he is a much-loved and cherished part of the family.''

The insider added: ''The party is going to be everything that the wedding in Italy was - lots of celebrating with champagne, an incredible five-course dinner and then lots of dancing until the early hours of the morning.''

The 53-year-old star was spotted arriving at Heathrow Airport in London for the festivities this morning (24.10.14).

An eyewitness said: ''George seemed very relaxed and casual, he was so low-key that hardly anyone recognised him! George looked very happy to be back in the UK and seemed excited about the prospect of being reunited with Amal.''

A large white marquee was erected at the five-star countryside hotel, which sits on 65 acres, for the private festivities in recent days, and crates of champagne, white lilies, purple orchids and mini white roses were delivered this morning.
