LOS ANGELES, CALIFORNIA: Rumer Willis was spotted taking her dog to the veterinarian a month after she announced her pregnancy. The 34-year-old daughter of Bruce Willis and Demi Moore rocked a casual look as she walked her dog to the veterinarian in Los Angeles on Monday afternoon, January 16. She had shared some adorable pictures on Instagram in December to reveal she was expecting her first child with her partner Derek Richard Thomas.

The 'Once Upon a Time in Hollywood' actress donned black leggings and a basic black shirt. She also wore a cuddly tan fleece overcoat that covered her growing belly and accessorized her outfit with a turquoise and lime green ombré beanie. She sported thick white socks over her leggings and slipped into a pair of cream Birkenstock shoes. The actress wore her hair in pigtail braids. Willis and her partner, an independent musician, shared a carousel of pictures on Instagram announcing that they were expecting their first child together on December 30.

Musician Thomas shared the post on his Instagram page as well, changing his profile picture to a picture of him kissing her stomach. Although they made their relationship Instagram-official only in November 2022, the pair had allegedly been dating for much longer. For Bruce Willis and Demi Moore, who divorced in 2000, this will be their first grandchild. Moore posted her daughter's picture with the caption, "Entering my hot kooky unhinged grandma era," on her Instagram handle.

The big news has reportedly given Bruce Willis the will to live longer. A source told RadarOnline that Rumer's pregnancy has made him ecstatic and has him working to build a relationship with his grandson as he struggles with violent aphasia. "He's determined to stay coherent and lucid for as long as possible so his grandchild can have some happy memories of a grandfather who was present and active in his or her life," the source stated.

Rumer Willis is well known for her roles in the movies 'Hostage' (2005), 'The House Bunny' (2008), 'Sorority Row' (2009), and 'Once Upon a Time in Hollywood' (2019). She made her Broadway debut in Chicago as Roxie Hart the following year after winning season 20 of ABC's 'Dancing With the Stars'.
