Singers Justin Bieber and Selena Gomez's relationship may have ended, but they reportedly still seem to monitor each other's Instagram accounts.

The former lovers appear to share posts on the photo-sharing website that seem implicitly connected, reports aceshowbiz.com.

After Bieber posted a photograph of himself cuddling his little brother on his Instagram page, Gomez followed suit by sharing an image of herself sleeping with a baby boy beside her.

The photograph resembles the one the "Baby" hitmaker posted and many of Instagram users noticed the similarity.

One of them wrote on the comment section, "Same as your post @justinbieber."

This is not the first time that fans have noticed that Bieber and Gomez have tried to communicate via the social media website.

Earlier this month after Gomez was spotted making out with rumoured boyfriend Niall Horan at actress Jenna Dewan's birthday party, Bieber posted a photo of a mystery girl named Cindy Kimberly presumably to make the "Come & get it" singer jealous.
