KEVIN'S DIVORCE TURNS NASTY PRENUP, CUSTODY BATTLE & SHOCK LOVE CHILD CLAIMS!

Cruel rumours are swirling as the Yellowstone star faces another marriage breakdown

Step aside, Brangelina! Hollywood is bracing itself for the next big split after Kevin Costner was "blindsided" by divorce papers from his wife of 18 years, Christine Baumgartner, earlier this month.

The 68-year-old actor's reps said in an announcement on 3 May, "It is with great sadness that circumstances beyond his control have transpired which have resulted in Mr Costner having to participate in a dissolution of marriage action."

RUMOURS ABOUND

Last week, Christine, 49, was spotted out with daughter Grace, 12, buying balloons for her son Cayden's 16th birthday in Montecito. The mum-of-three, who is seeking joint custody of their children, including 14-year-old son Hayes, has cited "irreconcilable differences" in the divorce papers. However, that hasn't stopped an onslaught of rumours, forcing Kevin to deny he had fathered a "love child" with a crew member on the set of Yellowstone.
