Lisa Armstrong appears to be single again after reportedly parting ways with her boyfriend, actor Grant Kilburn, earlier this month.

The speculation intensified after Armstrong shared a Valentine’s Day Instagram rhyme celebrating those “on their own,” which many fans interpreted as a pointed message in the wake of the apparent split. 

According to Daily Mail, friends had previously described the couple as “happier than ever,” but insiders now say they quietly went their separate ways after deciding the relationship “wasn’t to be.”

Armstrong’s social-media activity comes amid a period of personal reflection following the recent death of Hurley, the much-loved chocolate Labrador she and her ex-husband Ant McPartlin adopted in 2013. 

Moreover, the 12-year-old dog, a constant presence through McPartlin and Armstrong’s high-profile divorce and custody discussions, was put to sleep earlier this week after suffering from illness. 

As per the outlet, both Armstrong and McPartlin were reportedly present for Hurley’s final moments.

Armstrong and McPartlin, who divorced in 2018 after 11 years of marriage, continued to share care of Hurley until the dog’s passing, with Armstrong posting a heartfelt tribute image on Instagram.
