For the non-'Trekkies' out there, Nichelle Nichols played Lieutenant Uhura on the original Star Trek TV show and movies. She is credited as being the first black woman to have a major TV role in which she wasn't a servant, and her kiss with Captain Kirk made TV history.

But today Nichols is best known for a photo she took with Barack Obama in the White House in late February that has just gone viral.

In the shot, the pair both flash the vulcan "Live long and prosper" hand gesture.

Obama has long identified himself as a 'Star Trek' fan. But there may be a bit more to the photo op. After meeting the president a little more than a month ago, Nichols tweeted:

Months ago, Pres. Obama was quoted as saying that he’d had a crush on me when he was younger. I asked about that and he proudly confirmed it!'

One would have to say Nichols is looking pretty good for 79. Does Michelle have anything to worry about it?
