Spears, 35, showed off her toned legs in a little black dress with long lace sleeves and a major cutout above her cleavage. Her long blonde hair was swept to one side, and she finished the look off with simple black pumps. Asghari, 23, looked trendy in white jeans, black high-top sneakers and a patterned navy button-up shirt.

The outing comes a little over a week after the pop legend took to her buzzed-about Instagram account to wish Asghari a happy birthday on March 3. In the post, Spears shared an adorable photo of herself posing with Asghari during a couples hike, a photo of his birthday cake and a silly Snapchat selfie with her man.

My baby's birthday πŸ’œ @samasghari

A post shared by Britney Spears (@britneyspears) on

"My baby's birthday," she captioned the Instagram slideshow.

Asghari and Spears have been enjoying each other's company since filming the music video, which co-starred singer Tinashe, back in November. Asghari plays Spears' hunky love interest in the playful clip, which sees her crawl towards him on a table before licking up (literally) spilled milk on the table in front of him.

Since then the pair has shared a handful of cute snaps together on Instagram and have been spotted on dinner dates on more than one occasion.
