Link Party: Ke$ha Apologizes to Britney Spears & Justin Bieber

 • It's been a busy day of I'm-sorrys for Ke$ha. She's  had to backpedal on talking crap  about  Britney Spears, saying she has "mad respect" for the singer. And she's also apologizing to  Justin Bieber   on her Twitter . The only thing she isn't apologizing for is  what actually matters .

• We feel kind of embarrassed for Joe Jonas watching him struggle through sit-ups . Can't he work out in a gym or on some private JoBro compound?

• Paris Hilton says she's not shopping around a reality show about her engagement...yet . Something to look forward to!

• Jennifer Love Hewitt is going through all the textbook breakup phases like crying to People and chopping off her hair . Sounds like someone could use a nice, long vagazzle session .

• Zoe Saldana looks adorable on the cover of Nylon , and she's not afraid to open up about Hollywood casting: "When they say 'We want to go white,' they have a very smooth way of saying it, and the recent one is the word traditional. [I've heard] 'Oh, you know, you're just not what we were looking for, your skin is a little darker.' Compared to what?! My skin is just my skin. It's dark if you compare it to someone who's lighter."
