Glasgow City took advantage of Hibs' first loss of the campaign to move three points clear of them at the top of the Scottish Women's Premier League.
Donna Paterson scored twice for Aberdeen and Rebecca Dempster added another as Aberdeen beat Hibs 3-0.
City hammered six goals without reply in their away game against Celtic.
First-half goals from Leanne Ross, Denise O'Sullivan and Hayley Lauder were added to by Julie Fleeting's hat-trick after she came on at half-time.
City head coach Scott Booth said: "I think we are making good strides forward all the time and the girls are putting into practice what they work hard on in training.
"Every week I feel we are getting sharper, doing the right things and cutting out errors.
"It was always going to be tough against Celtic today if we didn't play with aggression and pressure and good decision making from the off.
"I think we started the game well and could have scored earlier than we did, but I felt overall the longer the game went on, the better we got."
Elsewhere, Stirling University beat Hamilton Accies 2-0 and Spartans were 2-0 winners over Rangers Ladies.
