Billie Lourd thanks Taylor Lautner, friends after Carrie Fisher's death

Jan. 25 (UPI) -- Billie Lourd is feeling grateful for rumored boyfriend Taylor Lautner and her friends.

The 24-year-old actress gave a shoutout to Lautner and her pals Tuesday on Instagram following mom Carrie Fisher and grandmother Debbie Reynolds' deaths in December.

"This group of onesie clad supremely supportive humans (and many others #notpicturedbutinthepicture) are the kings and queens of my world #gratefulfortheirgreatness #friendsfindingthefunny," she wrote.

Fisher died at age 60 on Dec. 27, and Reynolds died at age 84 the next day. Death certificates released this month said the actresses died of a heart attack and a stroke, respectively, although Fisher's death remains under investigation.

"Receiving all your prayers and kind words over the past week has given me strength during a time I thought strength could not exist," Lourd said Jan. 2. "There are no words to express how much I will miss my Abadaba and my one and only Momby."

The Scream Queens star paid tribute to her mom Jan. 11 with a throwback photo on Instagram. She was later spotted with Lautner on a trip to Cabo San Lucas, Mexico.

"She has been very happy," a source told People. "You can tell she is having a good time. Taylor is taking great care of her. They seem very happy together."

Lourd and Lautner were first linked in December after meeting on the set of the Fox series Scream Queens. The pair played love interests Sadie Swenson, aka Chanel #3, and Dr. Cassidy Cascade in Season 2.
