(CNN) - First lady Michelle Obama on Friday answered criticism of her surprise appearance during the Oscars earlier this week.
"That is just the nature of life," she said in an interview that aired on NBC's "Today." "We live in a time when there are bloggers and tweeters and 24 hour news and everyone has a voice in this, you know, in this town square and it is a big one."
Some didn't consider Obama's late-night cameo, which came live via satellite from the White House, very appropriate.
"Seriously, if (the left) really had their president's interests at heart, they'd steer away from encouraging these celebrity appearances. It makes both the president and the first lady seem small and grasping. In this case, it was just downright weird," wrote conservative columnist Jennifer Rubin at the Washington Post.
Those refrains were echoed by a number of conservative blog posts and commentators online.
Brushing it off, the first lady said that while the expanding online dialogue is good overall, "that means that at any point in given time somebody is not going to like what you do."
Obama is on tour to promote her "Let's Move" campaign against childhood obesity. A coordinated media push over the last week has included stops on Jimmy Fallon's late-night comedy show and events in Illinois, Mississippi and Missouri. She also taped two public service announcements with one of Sesame Street's biggest stars, Big Bird.
Obama was also asked–again–about her now-famous bangs.
"It is a hair cut. I am sorry. I don't know what to tell you," she responded curtly.
When she was reminded she had teased earlier in the week that her bangs were a result of a midlife crisis, she said "that was a joke."
"But it is really a hair cut," she said. "I have cut my hair before...I cut it shorter. I had it shorter two years ago. So this is just a cut in the front."
