Celtic Women made it three Old Firm victories out of three in the SWPL after they cruised to a 3-0 win at the Hummel training centre.
Sarah Ewens, Josephine Giard and Katherine Smart all scored as Celtic closed the gap on second-placed Hibernian to three points, having played a game less.
Hibs lost 3-1 at home to champions Glasgow City.
City had already claimed their 13th title in a row in midweek.
It was a dramatic end at Ainslie Park, with Hibs thinking they had equalised in the 86th minute only for the goal to be ruled out for an apparent foul in the build-up. Two minutes later their misery was compounded when Jordan McLintock scored City's third.
The win for Scott Booth's side will give them a huge confidence boost ahead of Thursday's visit of Brondby in the last 16 of the Champions League as they bid to defend a 2-0 first-leg lead.
They also meet Hibernian again on 24 November in the Scottish Women's Cup final.
Frustration in promotion race
In SWPL 2, no-one was able to take the initiative in the battle to be promoted to the top flight.
Rachel Walkingshaw's goal with 20 minutes to go salvaged a draw for leaders Hearts away to Kilmarnock.
But Hamilton Accies head coach Gary Doctor was left lamenting a disappointing second half from his side after they let slip two late goals to Dundee United to draw 2-2, leaving them still three points behind Hearts.
That means Hearts could secure promotion next week should they beat Glasgow Girls and Hamilton failed to win at home to St Johnstone.
