Before they were the powerhouse designers behind The Row and Elizabeth and James and massively famous throughout the world, Mary-Kate and Ashley Olsen were just spry child actresses and mini moguls, appearing in their own movie franchises.
Actor Steve Guttenberg famously worked with the twins on one such flick, playing father figure Roger Callaway in 1995's It Takes Two. The story of young girls who end up switching places debuted when the Olsens were just 9 years old, but already had years of acting under their belt with Full House and TV movies such as How the West Was Fun and To Grandmother's House We Go.
"They were adorable," Guttenberg said of the Olsen twins, now 28, on HuffPost Live on Wednesday, Aug. 6. "They came to my house one time for a little pool party. They were great kids. Their parents were terrific, lovely kids."
"They were very, very balanced and stable kids," the Affluenza actor, 55, continued of his former costars. "I remember having races with them for a quarter. I knew they were worth a billion dollars but I'd go, 'For a quarter, we're gonna have a race!' I'd win, cause they're worth a billion dollars, I'll take the quarter."
After working with Mary-Kate and Ashley almost 20 years ago, the famous twosome is still a part of Guttenberg's life. "They were great kids and once in a while I'll see them," he added.
When he does see them, Guttenberg said he has no problem telling the twins apart, spilling that "one of the girls has something a little distinguishing on her face."
He wouldn't reveal what the distinguishing mark was, however, as he explained, "I can't say! I don't know if the girls want me to say but she has a little something."
