'Breaking Dawn' Actor Kiowa Gordon, Katherine McPhee Celebrate Birthdays In Today's Tweet Dreams

From Sarah Jessica Parker to Aretha Franklin (as Questlove tweeted to her, "#HappyBdayAreatha she is the Queen PERIOD") today was chock-full of celebrity birthdays. Among the many stars celebrating their March 25th births was Katherine McPhee, who received plenty of Twitter love, including from actress Ashley Madekwe, who posted, "@katharinemcphee Happy Birthday lovely! xo." Katherine, who turned 27 today, wrote, "Thk u to everyone makin me feel real special! Love birthdays! & Love u all!" There was also some b-day love for Aly Michalka, including a tweet from her sis AJ Michalka, who told her, "Happy 22nd Birthday to my unbelievable sister...I could not love you more Aly..."

In addition to all these, there's also a "Twilight"-related birthday today! Kiowa Gordon, or as he's better known to Twi-hards, Embry Call, turned 21 and got a whole lot of well-wishes on the social networking site. It seems Kiowa (pictured) and his co-star Tinsel Korey were taking the wolf pack to Las Vegas for some celebrations, when she shared, "Happy 21st Birthday Precious!!! @Circakigordon See you tomorrow!!! #KGTKVegas2011BdayWknd." Here's hoping they run into "The Hangover" wolf pack!
