Sen. Barack Obama wasn’t the only one celebrating his winning the Democratic presidential nomination last night.
A source tells E! that Obama supporter Ryan Phillippe expressed his excitement by buzzing friends with text messages Tuesday night.
“Amazing night, amazing results,” one of Phillippe's messages read.
E! has also learned that Phillippe last night was saying he plans to help Obama's campaign for the general election in November.
In February, Phillippe was seen wearing a Barack Obama T-shirt.
Other celebrity Obama supporters include Oprah Winfrey, Will Smith, George Clooney, Halle Berry, Ben Affleck and Robert De Niro.
