Jennifer Aniston to be a great aunt after her niece Eilish Melick reveals she’s expecting a baby

Jennifer Aniston’s niece Eilish Melick is expecting a boy this summer, making the A-lister a great aunt-to-be.

Aniston, 52, is the younger half-sister of Eilish’s dad John Melick III, 61, an assistant film director, as they were both born to the late Nancy Dow, who died in May 2016 at 79.

The perennial A-lister is an aunt to Eilish, Eilish’s younger brother John Melick IV, as well as half-brother Alex Aniston’s children Ryat and Kira.

Eilish Melick, 24, and her husband Sean Nebbia, 25, posted to social media about expecting their first child in December, The Sun was first to report.

The couple recently celebrated their two-year anniversary, according to the outlet, and are both Navy veterans.

In a post last month, Melick showed off her baby bump, captioning the image, ‘Oooh baby, baby.’

She has past dabbled in show business, having appeared in TV films such as High School Possession, Runaway and Summoned.

The Morning Show star opened up on the topic of having children in July of 2016 during a time she was still married to now-ex-husband, The Leftovers star Justin Theroux.

‘We get to decide for ourselves what is beautiful when it comes to our bodies,’ she said in an op-ed for The Huffington Post. ‘That decision is ours and ours alone. Let’s make that decision for ourselves and for the young women in this world who look to us as examples.

‘We don’t need to be married or mothers to be complete. We get to determine our own “happily ever after” for ourselves.’

Aniston, who played Rachel Green on the 90s NBC hit Friends, said that she ‘may become a mother some day,’ adding, ‘Since I’m laying it all out there, if I ever do, I will be the first to let you know.

‘But I’m not in pursuit of motherhood because I feel incomplete in some way, as our celebrity news culture would lead us all to believe.’
