Rumer Willis shared the news online saying that her newborn daughter, who she shares with partner Derek Richard Thomas, was ‘pure magic’.

The Alzheimer’s Society has said that after Willis’s diagnosis of dementia was announced they saw a 12,000% spike in visits to their website.

The Hollywood actor sang happy birthday alongside his children, his wife Emma Heming and former wife Demi Moore.

The actor’s daughter confirmed the news on Instagram.

Jennifer Flavin Stallone and daughters Sophia, Sistine and Scarlet will star in the eight-part series The Family Stallone.

In March, Willis’ family announced he would be ‘stepping away’ from his successful acting career after having been diagnosed with aphasia.
