They've been rumored to have broken up for a while now.

And while both Pia Wurtzbach and Marlon Stockinger have maintained that they are doing just fine, fans now have a new reason to worry after the couple decided to wipe traces of each other from their respective Instagram accounts.

The two have deleted all images of them together from their accounts, including a shot of them cuddling while on a vacation in Hawaii and a photo in which Stockinger reassured their followers that "nothing's changed" between him and the Miss Universe 2015 winner.

Their decision to delete memories comes more than a month after Stockinger unfollowed Wurtzbach on Instagram.

Stockinger, at the time, explained that he and Wurtzbach are now just keeping their romance more private.

"It's always good to show everything, a lot in the beginning but what matters is the two of us in the end behind closed doors. We don’t always have to show that or share that either," he said in a previous interview.

However, the recent deleting spree has become a reason for their fans to panic.

Stockinger and Wurtzbach's relationship was first rocked when a model surfaced and alleged that he is the father of her twin kids.

The model said she gave birth to her and Stockinger's daughters back in 2009, when the racecar driver was only 18.

She added that she has been raising the kids alone, but stressed that she is not asking for any financial support from Stockinger and his family.

Wurtzbach and Stockinger first confirmed their relationship in an interview with ABS-CBN News' Dyan Castillejo in January, with the beauty queen saying that she's lucky to have found "somebody who’s very secure with himself and who understands [her] job."
