Ashley Cole desperate to start family with ex-wife Cheryl.

Ashley Cole is leaving no stone unturned in trying to woo back ex-wife Cheryl and is reportedly looking for the "biggest diamond he can get" to propose to her for a second time.

The soccer ace, who separated from the 28-year-old singer in 2010 amid claims that he had cheated on her with five women, wants to re-marry her and is now hunting for the ring to get down on one knee, so the pair can start a family, reported Sun online.

"He is convinced Cheryl will agree to marry him and wants the biggest diamond he can get. She`s desperate to start a family but he knows she`ll want to do it as a married woman," a source said.

Cheryl who has had a makeover with newly blonde hair following her sacking from the US version of `X Factor`, is also spending time with Ashley`s mother Sue at her home.

"Sue is incredibly fond of Cheryl and is forever singing her praises. She says she is so glad to have her daughter-in-law back. She realises how insanely happy Cheryl makes Ashley and believes they are a good team. Sue saw the positive impact which Cheryl had on Ashley," the source added.

However, Cheryl`s mother Joan is not so keen on the reunion and was upset seeing them together at the Girls Aloud star`s 28th birthday party.

"Joan has Cheryl`s best interests at heart. She is the person who is most open and honest with her and was there to pick up the pieces when they split," the source said.
