Michelle Obama shows off her Barack impersonation

US First Lady Michelle Obama has told The Late Show host Stephen Colbert that the entire Obama family does impressions of the President.
She even showed off her own version, mimicking Barack Obama's boring dinner table conversation.
The popular First Lady also weighed in on her friendship with pop superstar Beyoncé.
"She's a sweetheart. She's smart, she's creative, she's a great mother. She loves her family," she said.
"She's just a low-key lady, so we have a lot in common in that way. Except I can't sing, I can't dance."
