Princess Beatrice's husband is sharing an office building with his ex.

Edoardo Mapelli Mozzi's property development and interior design company Banda is located in Kensington and when a space opened up in the same building, Dara Huang - who is the mother of his son Christopher, four - relocated her architectural firm, Design Haus Liberty, from Clerkenwell.

A source told the Daily Mail newspaper: '' Edo was already a tenant there and when the space below him became available, he recommended it to Dara.

''He felt like it made a lot of sense: They get on very well and intend to stay close as they are raising a child together.

''Bea has nothing to worry about . She has no secret wish to get back together. Plus, she actually quite likes Beatrice.''

Following the announcement of Edoardo and Beatrice's enagement, Dare said in a statement: ''I wish the best for Edo and Beatrice and look forward to uniting our families.''

Meanwhile, it has been revealed that Beatrice, 31, is a ''hands-on'' stepmother to Christopher, known affectionately as Wolfie.

A source told PEOPLE: ''Beatrice is a wonderful and very hands-on stepmom. He is very much part of their life.

''Edo is easily one of the best dads, he is so involved, and Beatrice is already showing that she's a fantastic step-mummy.

''They've been on family vacations together [with his son]. They are really happy.''
