It’s all a bit convuluted and messy because Kate scrubbed her insta a week ago and is posting and deleting but she is now using the platform to accuse Sheen of cheating and abuse.
The background:[Rough timeline, don't come at me.]
- Sheen and Beckinsale met when they were nobodies and were a couple for years as their careers were on the rise
- They had one daughter together (Lily)
- They never married
- While working together on Underworld they formally split with Kate going on to marry the director of that film: Len Wiseman
- There might have been overlap/cheating on Kate’s end but Sheen always denied this.
- Sheen/Beckinsale/Wiseman appeared to be close and committed coparents for years.
- After a decade of marriage Beckinsale/Wiseman divorced.
- They’ve never commented publicly on it but Sheen now appears to be somewhat estranged, or at least less public with Beckinsale and their daughter. This rift seemed to occur around the time he announced his pregnancy with his current partner, who is only a few years older than Lily. Prior to that Beckinsale/Sheen/their daughter would all at least somewhat consistently mention each other or show up in each others social media

From her stories:

In the above posts Kate implies:
- She was cheated on repeatedly by the father of her child (Sheen)
- She only found out years later when married (to Wiseman)
- Sheen cheated on her while she was pregnant and giving birth
- Sheen was abusive to her because of his guilt over cheating
