The heated drama between Real Housewives of Orange County star Tamra Barney and ex-husband Simon Barney continues, with Simon now lashing out at Tamra on Twitter.

Tamra has taken Simon to court recently to allow their kids to appear on the show with her, despite Simon's efforts to keep them off the show. The two have exchanged harsh words back and forth over the issue.

Now, there is a new source of beef between them, as Simon tweeted recently about Tamra failing to pick up their eight-year-old daughter. 

"Tamra, school called," Simon tweets. "You didn’t pick up Sophia. On my way to get her. No response from you from school or me. Are you okay? Where are you?”

When a Twitter follower thought it was inappropriate for Simon to post this on Twitter and that he should have tweeted to Tamra, he wrote, "I did text, and so did the school. Was hoping to get response from Twitter. Btw, she's fine & was home."

Tamra responded on Twitter, writing, "Unfortunately, due to the holiday schedule, our weekends switched, and I overlooked it. Totally my fault and felt horrible.”

Do you think it's inappropriate for Simon to post this on Twitter?
