Two hot topics on Twitter today (Aug. 22): how much everyone seems to love the apocalyptic comedy 'At World's End' and the coming out of Wentworth Miller. But more importantly, Nathan Fillion covered himself in kittens! Day made.

Newly engaged and newly pregnant actress Jennifer Love Hewitt showed off her burgeoning baby bump on the red carpet of the Pampers Love, Sleep & Play campaign -- and revealed a new haircut to boot.

Today is Aug. 21, and it's also hump day. The stars weren't so much interested in hump day, but they were talking about political topics, celebrity birthdays and announcements about their various careers. Maybe next Wednesday, Twitter.

If you follow Patton Oswalt on Twitter, you hopefully noticed that he pulled off the greatest Twitter troll probably ever over the weekend.

It all started innocently enough, with a Lady Gaga fan getting super excited that celebrity gossip blogger Perez Hilton was spotted in the lobby of Gaga's apartment building. Until Lady Gaga took this news and freaked out, calling security and then raging against Hilton on Twitter in all caps, going so far to accuse him of stalking her.

'Bachelor' and 'Bachelor Pad' star Gia Allemand passed away at the too early age of 29, which has prompted an outpouring of emotional reactions to the news, as well as thoughts for her friends and family during this difficult time.

Today (Aug. 12) was the day of Gaga, with Mother Monster tweeting ad nauseum about her brand-new single, 'Applause.' But that didn't mean that's what the rest of the celebs were talking about.

Lady Gaga is not about to be one-upped by Katy Perry. The two pop stars were both victims of hackers and leakers who released their highly anticipated music to the masses early, so Gaga responded to the hype by sharing her song in full on her own to her beloved Little Monsters -- who were trying to steal the thunder from Perry's 'Roar' as best they could.

Today (Aug. 8), the hot topic of the day was "OH MY GOD, WHAT DID BEYONCE DO TO HER HAIR?!" Hint: It's either a wig, or that's how short her hair is without wigs and weaves. It's also Throwback Thursday, so there was a bunch of that too.

After years of speculation, former 'Cosby Show' and 'That's So Raven' star Raven-Symone has come out of the closet -- and in a true sign of the times, she did so over Twitter.
