The frequent reality stars have been married since 2009 and judging from yesterday's PDA, they are just as loved up as ever!
Heidi puckered up to her man outside the AOL studios in New York, during a day of promo for their new reality series Marriage Bootcamp.
The couple joined other US reality stars for the WE tv series, which forces married couples to confront the issues that threat to push them apart.
For Speidi, it was the issue of babies, with Heidi keen to start a family and Spencer "baby blocking" as he didn't want kids.
Yesterday, however, they announced a major surprise: Spencer has changed his mind and now wants to have children!
The couple revealed they have agreed on a "timeline" to start having children – although Heidi is pushing to have the timeline brought forward!
Heidi and Spencer met and fell in love on MTV reality show The Hills, culminating in a televised wedding in 2009.
After the show ended, they went on to appear on other reality shows including America's version of I'm A Celebrity… Get Me Out Of Here, and Celebrity Big Brother.
