While 1D's Louis Tomlinson is happily expecting the arrival of his first baby, it seems the pop megastar has sparked the rumor mill anew with news of him setting his eyes on The Originals star, Danielle Campbell.

The 23-year-old soon-to-be-dad was allegedly seen taking a quick trip to the Hollywood hot spot Millions of Milkshakes with Danielle, where he was being playful and flirty. The couple apparently has a massive sweet spot as they ordered four different milkshake flavors: Oreo and cookie dough, Reese's Peanut Butter Cups with cookie dough, Ferrero Rocher and strawberries and Nutella.

A fan managed to sneak a stealthy pic of the pair sitting side by side as they waited for their milkshakes.

This sighting comes a couple of weeks after Danielle's pal, Keelin Woodell snapped a pic and posted an Instagram of the group hanging out at favorite Hollywood hotspot, Bootsy Bellows.

Danielle is most known for her role as the Witch Regent in the CW hit spinoff series, The Originals.

Louis Tomlinson is one-fourth of One Direction, who earlier this year broke up with his longtime girlfriend Eleanor Calder. Not long after their split, news of Louis expecting a baby with stylist Brianna Jungwirth started to circulate. While Louis and Briana have never expressly declared that they are a couple, the two are apparently good friends and want the 1D singer wants to be as hands on as much as possible when it comes to becoming a dad as well as a pillar of support for Briana throughout her pregnancy.
