Rumer announced in December that she is expecting her first child with her partner, Derek Richard Thomas, and showed off her baby bump in a chic tight dress on Sunday.
The 34-year-old was joined by her mother, Demi Moore, 60, and stepmother Emma Heming Willis, 44, as she was showered with gifts for the occasion.
Also enjoying the festivities were Rumer’s sisters, Scout, 31, and Tallulah, 29, and her half-sisters, Mabel, 10, and Evelyn, eight.
The blended family is notoriously close, and all seemed to beam with pride as they prepare to grow their clan by one more member.
Unfortunately, Bruce, 67, was not in attendance as the star continues to grapple with his progressing frontotemporal dementia diagnosis.
