Julianne Hough — New BF Delivers After Walk of Shame

It”s getting serious … Julianne Hough“s face-sucking new bf performed the walk of shame from her place this weekend — but followed up like a champ by sending her flowers.

Ryan Seacrest“s replacement is Ari Sanders — an Oscar-winning director. We posted pics of the couple getting hot and heavy in a restaurant … and it appears they”ve upgraded to sleepovers.

Shortly after Ari reportedly left Julianne”s West Hollywood pad early Saturday morning — which also happened to be her 25th birthday — he was seen walking into a flower shop … but leaving empty-handed.

Walk of shame sources tell us a short time later … JH got a knock at her door and a fresh bouquet of red roses.
