Neil Patrick Harris is one proud papa. The “How I Met Your Mother” star spent family time with his partner David Burtka and their six month-old twins, Harper and Gideon, this weekend.

He shared a picture of their familial bliss, which appeared to be taken in the twins’ nursery.

“Relaxing on a Sunday afternoon. My heart is full of love,” he said via Twitter, as he shared the smiling snapshot of his longtime love with their baby boy and girl.

The couple welcomed the new additions to their family last October, with the help of a surrogate. Harris heralded their arrival via Twitter.
