Calvin Harris has been exceedingly busy scoring points with girlfriend Taylor Swift's mom.

US magazine reports the 31-year DJ recently spent the days following Swift's 26th birthday hobnobbing with her parents. If photos taken of a recent gathering at the "Bad Blood" singer's Beverly Hills home are any real indication of how things went, Harris seems to have already hit it off big with mom Andrea.

The two were pictured standing side by side, with her at one point cheerfully laughing back and forth as she and Harris conversed. Later in the evening, the happy couple took part in a Christmas-themed birthday bash at Apple executive Jimmy Iovine's Malibu home, where they also posed for several funny pics with Santa as Andrea approvingly looked on.

Swift has been long known to be close to her family, especially her mom, who was diagnosed with cancer earlier this year.

Roughly eight months ago, Andrea presented her daughter with the ACM Milestone Award, where she remarked in her speech, "For many years, I was her constant companion. And I witnessed a young girl with very few friends become a young woman with many, learning to stand up for herself and the things she believes in."

The proud mom also marveled about her daughter has grown to be brave enough to explore her musical curiosity enough that it allows her to have "a voice against those who hate, and giving of herself to those in need."

Meanwhile, with her 1989 Word Tour also recently coming to a close, Swift and Harris recently hinted they plan to spend the next several days reaffirming their affinity for one another.

A source told Hollywood Life, "Calvin and Taylor have hardly seen each other since she began her 1989 World Tour, so they want to make up for lost time."
