"Nicole wants a fresh start," a source told the Sun. "That means getting rid of all memories of Liam. She can use the money she makes on it to buy an amazing new pad."
Nicole and Oasis singer Liam's five-year marriage came to an official end in April, when they were granted a divorce in just 68 seconds at the Principal Registry of the High Court in London.
Liam had previously admitted adultery and fathering a child with American journalist Liza Ghorbani.
