Saoirse Noonan scored her 25th goal of the season
Celtic comfortably beat Hearts to move up to fourth in the SWPL and to within three points of leaders Glasgow City.
Shannon McGregor headed in a Morgan Cross delivery for Celtic's opener.
Another header, from Saoirse Noonan, doubled the hosts' lead following Amy Gallacher's free-kick. It was Noonan's 25th goal of the season.
Cross added her name to the scoresheet with a tap-in after enterprising play on the left by Hana Kerner.
Natalie Ross robbed Lisa Robertson and ran through to slot home Celtic's fourth on the hour.
Substitute Abi Harrison set up Cross but the winger could not add to her tally, with the ball coming back off the post.
Elena Sadiku's reigning champions, who have a game in hand, are a point below Rangers and Hibernian and are three points clear of Hearts, having moved above the Edinburgh side in the table.
