They have an unusual connection, yet they have kept their Hollywood friendship mostly under the radar for years.

But Brenda Song changed that on Wednesday when when she wished her pal Paris Jackson a happy 26th birthday.

The women are bonded not just by friendship, but by family, as Brenda’s fiancé Macaulay Culkin, 43, is the godfather of Paris, as well as her brother’s Prince and Michael Jr.

In the photo shared by Brenda — who celebrated her birthday only days earlier — the Dollface actress stood in a what looked like a hotel entranceway. Paris, who was considerably taller than Brenda, playfully rested the side of her face on the top of her friend’s head.

Brenda wore an all-black ensemble with a tasteful brown handbag, while Paris wore a cream-colored cardigan and black pants.

The birthday girl had a long scarf draped from her throat, and she had a cigarette perched between her fingers as she smiled for the photo.

‘Happy birthday @parisjackson,’ Brenda wrote on the pictured. ‘I miss you and our Parisian adventures. Love you so much!’

The caption didn’t appear to be just a pun, as Brenda and Paris have previously been spotted spending time together in the French capital.

Back in 2017, the year that she began dating Macaulay, Brenda and her partner were seen dining out with Paris in early December after enjoying a week in the City of Lights following Thanksgiving.

Brenda and the Home Alone star were linked in July of that year after they were seen having dinner at the celebrity hotspot Craig’s in West Hollywood.

The lovebirds later expanded their family with the birth of their first son Dakota Song Culkin on April 5, 2021.

Dakota’s name hold’s special significance for his father, as he’s named after Macaulay’s late sister Dakota Culkin, who was killed in 2008 when a car hit her as she was crossing the street.

In March of last year, it was reported that they had secretly welcomed a second son, reportedly named Carson, around Christmas of 2022.

The happy couple also took a step toward marriage when they got engaged in 2022, though it’s not yet clear when they plan to wed.

Paris and her godfather Macaulay spent some time together just a few months ago when she celebrated the unveiling of former child actor’s star on the Hollywood Walk of Fame.
