Mom-of-three Denise Richards shared some shots of her equestrian daughters.

“Lola & her pony lily @gigisaffronever right before her 1st show! 1st place, 3rd, reserve champion,” the proud mom captioned the above photo via Instagram.

She added another photo, writing, “Sami on her pony Hansel before her 1st show..so proud of our girls they came home with a few ribbons & were so cute!”

And last week, the actress and her daughters were seen leaving gymnastics class in Thousand Oaks, Calif.

After the girls’ father, troubled actor Charlie Sheen, called on his Twitter followers to deliver “dog s–t” and “rotted egg” to Sam’s school because she was allegedly bullied, the L.A. private school has fired back.

“Viewpoint School’s highest priority is the safety, security and education of our students. Like all responsible schools across our nation, we are concerned when any individual uses a social media forum to encourage actions that may risk the safety and security of any school,” a statement read.

“The parent of a former Viewpoint School student who has not attended Viewpoint School since March 2012 has made certain accusations in the media. Viewpoint School first became aware of these accusations last year,” the statement continued. ”Our administrators addressed the issue appropriately at that time. Our School takes accusations of bullying very seriously. For over 50 years, Viewpoint School has provided a safe and nurturing environment for our students to thrive, and we will continue to do so.”

And according to TMZ, some of the parents of Viewpoint have rallied to get Charlie prosecuted for his online rant.
