Ellen DeGeneres Fights Back, Serena Williams Gets Serious: Celebrities on Twitter

I love celebs. I love Twitter. So I really love today's celebrity Tweets! Here's what they've been up to lately.

What the! Who would hate on the lovable Ellen DeGeneres? She Tweeted this clip of a rude guy on Family Feud, and later tweeted videos of her mom's response (spoiler alert: her mom was none too pleased with the Family Feud dude).

Yikes and ew, Jim Carrey! I guess now that you're single, the floodgates have opened on the gross jokes? (OK, so I snickered -- that is NOT the point!) Actually, sorta nice: Later he tweeted that jokes are jokes, but Tiger should just be allowed to play golf without all the judgment. Uh oh, a little insight ...?

Moms can be so embarrassing -- when they're not US! Nicole Richie tweets this link to an adorable '80s-era photo of her and her mom ... So how is she going to make sure she never embarrasses Sparrow? (Oh man, too late ... she already named him Sparrow!)

Questlove, percussionist for The Roots, the in-house band for Late Night with Jimmy Fallon, and a truly prodigious Tweeter, posted this great web-only performance of Suzanne Vega doing Tom's Diner:

Finally, Serena Williams sends a shout-out of hope and support to legendary tennis pro Martina Navratilova. Super-nice and gracious, and of course we echo the sentiment.
