The actress split from the former Baywatch star in 2006 after 16 years of marriage, but they've struggled to remain on friendly terms since their divorce.
Now Bach has hit out at her ex, claiming he has ""other"" women apart from his Welsh girlfriend Hayley Roberts and accusing him of ordering his aides to keep Bach away from him at public events.
She tells Britain's OK! magazine, ""We should (speak) because (our daughters) shouldn't be put in the middle. At their recent T4 On The Beach concert (in the U.K.) he didn't even say hello.
""I ran up to see my girls but before I got to them a woman who works with David stopped me and said: 'David doesn't want you around.' I said: 'Excuse me, sweetheart, I didn't come here to see David, I came here to see my daughters.'... I admire him. He's the father of my children and I will always love him for that. But he's just not friendly to me right now.""
Asked her opinion of Roberts, Bach replies, ""Which one? She's the girl he's showing to the press but I know there are others in America. It's funny he did those Baywatch pictures with her, maybe he should do a shoot for something more current - Baywatch ended eight years ago (sic).""
