In 2011, when Bellizzi was pregnant, it was reported that the baby was Mel Gibson’s love child, though he vehemently denied the claims.

Bellizzi also refuted the rumors to TMZ in November 2011, saying: ‘Mel Gibson is not the father of my child.’

In response, a spokesperson for Reum told said: ‘The people who this story matters to have known about it for 10 years. Carter supports this child. While he does not have a traditional father-daughter relationship with her, he has provided for her since she was born, and will continue to do so.’

Bellizi has kept a low profile since hitting the headlines with Gibson in 2011.

The reality show, VH-1’s Secrets of Aspen, that she appeared on in 2010, only ran for one season and she has not appeared on any other shows since.

A source close to the situation added to the outlet that her daughter had been ‘triggered’ by seeing Reum’s lavish wedding to Hilton, and felt ‘left out’ of her father’s life.

The source said: ‘Also, she saw the articles of Paris and Carter talking about starting a family. She felt tremendous rejection and felt left out. She wants to have a relationship with him.’

Reum is worth an estimated $40million, after co-founding investment company M13 with his brother Courtney Reum. Meanwhile, Reum’s wife Hilton is worth an estimated $300million.

The source continued that Reum’s daughter wants to ‘know her daddy.’

‘She just wants to really complete the missing pieces of her puzzle,’ the source divulged.

‘She’s at that age where self-identity is so important, and children want to know who they are and where they come from. It’s important for him to help her with that.’

‘It’s not about [Reum] or the mother. It’s about making the child whole. She is absolutely an amazing little girl. She has so much love to give. And she wants to give it to him, his family and whoever he chooses to love.’

A second source told the outlet: ‘She is of an age now where she is cognizant and wants her paternal family to hear her and know her. He may not claim or love her, but she claims and loves him and his family.’

Hilton has made no secret of her plan to start a family with Reum of their own, now they are married.

‘We have been doing IVF, so I can pick twins if I like.’
