Chris Martin admits he’s ‘sad’ about being an empty nester as kids with ex Gwyneth Paltrow are away at college

Chris Martin admits he’s struggling a bit now that both of his children have flown the coop.

The “Coldplay” frontman — who shares son Moses, 18, and daughter Apple, 20, with ex-wife Gwyneth Paltrow — confessed that being an empty nester makes him “sad” in a new interview with Rolling Stone.

“It’s sad. That’s the only word,” he said, when asked what it’s like to have all of his kids out of the house.

“But of course, it’d be weirder if they were still like, ‘I can’t leave,’” he admitted, adding, “Then you’d be more worried.”

His youngest child moved out earlier this year after starting college at Northeastern University in August, while his eldest kid is a junior at Vanderbilt University.

Fortunately, the family was able to reunite in Paris for Apple’s debut at the star-studded Le Bal Des Débutantes earlier this month.

The rock star said that the ball is “so not something I ever thought I’d do, but because I’m so in love with her, I’m like, ‘OK.’”

Martin admitted that he likes his children “very much” before joking that “they’re not biologically” his.

“My favorite new thing to embarrass my son is, if we’re walking down the street and someone comes up to us and they say, ‘I’m sorry to disturb you while you’re with your son,’ I say, ‘That’s not my son. That’s my partner,’” Martin said with a laugh.

“Yeah. I like them a lot. I think they are mine, to be fair,” he added.

Martin and the Goop founder, 52, tied the knot in 2003 but famously announced their “conscious uncoupling” in 2014 after nearly 11 years of marriage.

Two years later, they finalized their divorce and have continued to amicably co-parent their kids.

Martin has since moved on with partner Dakota Johnson. He refused to comment on recent rumors that he and the “50 Shades of Grey” actress, 35, are engaged.

“It is important to say that [romantic love] is such a big factor in everything, even though it feels right to keep it precious and private; I’m not denying its power,” he said of their relationship.

Paltrow, for her part, married “Glee” co-creator Brad Falchuk in 2018 and became a stepmom to his two kids — Isabella and Brody — from his previous 19-year marriage with Suzanne Bukinik.

The “Talented Mr. Ripley” actress admitted in March that merging families and becoming a step mom was initially “really rough.”
