Clint Eastwood is said to have started a new romance with Christina Sandera
The source added, "Clint's kids have all met Christina and like (her). The kids all say she is 'normal'."
It's thought this is Clint's second relationship since splitting from Dina Eastwood last August. The 84-year-old's estranged wife filed for divorce in October 2013 after 17 years of marriage, citing irreconcilable differences.
The couple were married in 1996 and have one daughter together, Morgan, 16.
Clint Eastwood and Dina
Just recently, Barbara Walters described Clint as 'the one that got away' as she opened up on her attempts to seduce the famed director, 30 years after initially turning him down.
"This is a sad love story," she said, during an appearance on The Tonight Show with Jimmy Fallon. "I did this interview with Clint Eastwood something like 30 years ago.
"He was very flirtatious and I was very taken (with him). He asked me if I wanted to have dinner… and I said, 'No, I have to work'. You know, I don't mix business with pleasure," the five-time Emmy winner recalled. "I could have been Mrs Clint Eastwood!"

When Barbara had the chance to meet the man again, at the recent premiere of his new film Jersey Boys, she was determined not to make the same mistake again.
"I thought maybe it's not too late," she said. "I'm not kidding! I really did. I put on the right outfit. The false eyelashes – the whole thing.
"He was… polite," she continued. "He was courteous. What's that expression? He was just not that into me!"
