"I never get choked up, but I'm really emotional right now,'' Serena said at the trophy ceremony.
On the verge of tears, she added: "I'm really, really, really happy. I'd like to thank my mom and my dad for helping me.''
Venus, who at 22 is 15 months older than Serena, paid tribute to her sister.
"I wish I could have been the winner. but of course you have a great champion in Serena and she has won all four Grand Slams, which is something I'd love to do one day,'' she said.
"So, yeah, I'd kind of be just like her,'' she said.
Awwww...I'm sure you'll win all four Grand Slams one day Venus.
