Selena Gomez knows what she's talking about! The selfie princess chatted all about "the power of the selfie" when she was on Jimmy Kimmel Live! last night.

When Kimmel asked about her constant presence on social media, "Do you feel like you are always doing a show?" The 22-year-old, "No ... I don't feel any pressure. ... All my friends are doing it. I am a part of the generation.

But Justin Bieber's sometime love, who donned a sexy white one-piece ensemble, did confess, "I will admit maybe it's too much."

Prior to the sit down, our photogs caught the petite cutie entering the Hollywood studio wearing a sophisticated navy dress. Big hair! Slit in her dress! Cleavage! Does anyone else think she looks like sexy single gal on the prowl at the wedding?
