See 'Hills' Alum Frankie Delgado's Baby Daughter Isabella

The new dad shared a heartwarming photo of the little girl he says has given his life 'meaning.'

Frankie Delgado is positively smitten with his baby girl Isabella -- and we can't blame the proud papa.

The former "Hills" star, who welcomed his first child with wife Jennifer Acosta in May, had only shared a glimpse of his newborn daughter's sweet little footsie...until now.

"3 months ago my beautiful wife gave my life meaning and brought baby Isabella into my world, #sheisgrowingupwaytoofast #daddyslilgirl #outfitnumber4," Lauren Conrad's confidant and Brody Jenner's BFF captioned the Instagram snapshot above. The tiny tot, who's being held up by her glowing mama while the duo relax in bed, looks super-stylish in a hot-pink dress with a white flowered headband and matching sandals. We can't see Isabella's expression, but Jennifer's joyful face says it all: this mother-daughter duo is truly enjoying the moment.

And while we're more than happy with the photo, there's something else we'd like to see: a love connection between Isabella and Kristin Cavallari's "precious peanut" baby Jaxon. In due time, of course -- but we wouldn't mind another Speidi-esque wedding in the future.

But back to the present: Frankie recently gushed about his bundle of joy and what fatherhood means to him. "My favorite thing in this world is being a dad..The feeling can't be explained," he said on Instagram, along with a photo of a lion hugging its cub.
