The 'Candy' singer will splash out on the holiday home for his wife Ayda Field, who is missing the sunshine of Los Angeles ever since the couple moved to London, reported Sun Online.
"Robbie, and particularly Ayda, have been feeling the effects of the cold in London over the last couple of weeks. They are accustomed to the sunnier climes of LA -- so they started talking about sunny holidays. Ayda has spent most of her life in the US so she loves the sunshine," a source said.
The couple are planning to raise their daughter Theodora Rose in Britain but Field has insisted they spent part of the year abroad.
"The long-term plan is for Robbie and his family to stay in the UK while he works on his solo career and daughter Teddy soaks up everything English, from friends to education.
"They've been looking at properties in the Bahamas because they've spent time there before and love the anonymity Robbie has there," the source added.
