While you were sleeping, the Williams sisters were getting their Grand Slam on at the Australian Open.

Serena Williams won her record 23rd Grand Slam singles title Saturday night, and her sister was right there on the court to giver her a congratulatory hug.

The all-Williams final - the first at the Australian Open since Serena won the first edition in 2003 -- went to the younger sibling 6-4, 6-4.

The Australian Open tweeted about Williams' victory.

"This was a tough one," Serena Williams said. "I really would like to take this moment to congratulate Venus, she's an amazing person she's my inspiration."

Williams has won 15 majors since last losing to Venus in a Grand Slam final, at Wimbledon in 2008. That was the seventh and last major title that the older of the Williams sisters won.

"She's made an amazing comeback ... I don't like the word comeback," Serena Williams said. "She's never left. She's been such a great champion."
