Nicolas Cage is helping to pay child support for his grandchildren.

The National Treasure star's son Weston Cage recently settled his divorce from second wife Danielle.

Documents relating to the split revealed the singer-and-actor will be handing over half of a 'monthly gift' he receives from his dad to his former partner and their two children, Lucian, four, and two-year-old Sorin.

According to The Blast, Danielle has sole legal and primary physical custody of the kids and Weston, who has been granted visitation, must pay $8,000 a month in family support.

The sum is taken from the $16,000 a month he gets from his famous dad and will be used to help with car payments, rent and health insurance for Danielle and the children.

The former couple both confirmed they understand that Hollywood star Cage is 'under no legal obligation' to make the regular payments to his son and that they could stop, or the amount change, at any time.

Weston is the actor's son with his former girlfriend Christina Fulton.

Danielle has previously been granted a protective order against Weston, which obliged him to stay at least 100 yards away unless it was during a visitation with the children.

Weston, 27, married for a third time in April to Hila Aronian, four months after they announced they had got engaged in May 2017.

Announcing his engagement, Weston claimed he had found 'true love' at last.

He wrote on Facebook: 'ENGAGED AT LAST. Finally true love is no longer a fantasy. I announce with unsurpassable honor, love and excitement that my one true and ultimate Queen and I are officially engaged as of May 25th and we have awaited this declaration eagerly and decided to celebrate it in the season of global festivity.

He was also previously married to singer Nikki Williams for a year before he met Danielle.
