This Week In Celebrity Tweets: Pink's Pregnant, Justin Bieber Flashes Rihanna

The best thing about Twitter might be the anonymous opinions you get from internet strangers. This week, Pink got a handful of random advice when she asked her "tweethearts" how to tell her dad she was pregnant. But thankfully she was joking--Pink didn't actually tell her dad she was pregnant on Twitter...we hope.

Other favorite celebrity tweets from this week include Justin Bieber marking the one-year anniversary since the debut of My World, Lady Gaga giving us subtle hints about her new album and Katy Perry promoting her new Purrfume. Ciara gives us yummy food tips, and Maroon 5's Adam Levine dukes it out with the hotel minibar. Photos, or it didn't happen, Adam (preferably shirtless).

Also this week: Rihanna gets a private showing of Justin Bieber's abs (and pleads with the Bielebers not to kill her), Taylor Swift flies around the world and Kanye West makes my life easy and tweets "the greatest tweet of all time." I think that joke is here to stay, folks.
