Pop star Peter Andre fought back tears, after being asked how he would feel if ex-wife Katie Price's new husband wanted to adopt his children.
The singer, who cut short the live interview on Sky News, said: "No-one is going to take my kids away from me."
Andre, who has two children with ex-wife Price, said he would go to court if such a situation arose. Sky presenter Kay Burley apologised to him.
It was revealed on Wednesday that Price and Big Brother star Alex Reid had wed.
'Disrespectful'
Reid and model Price - formerly known as Jordan - announced their marriage, in Las Vegas, on Wednesday.
During Andre's marriage to Price he volunteered to adopt her first child, Harvey, whose father is footballer Dwight Yorke.
As part of the Sky News interview, Andre was shown archive footage of Yorke criticising him for wanting to adopt his child.
Responding to the clip, Andre said: "To me, a nice little thank you would be nice. I asked to adopt him because I love him. I didn't ask to adopt him to be disrespectful.

"It angers me when people turn around and I get a comment like that."
Burley then asked the star how he would feel if Reid said he wanted to adopt Andre's children, Princess and Junior.
"No-one is going to take my kids away from me - nobody," he responded.
"Nobody is going to take my kids away from me and I will fight to the death for that.
"I didn't expect that, I'm sorry. I will die for those children."
Ms Burley attempted to change the subject asking the visibly upset singer about his forthcoming tour - which Andre appeared on the show to promote - but he cut short the interview.
Blinking back tears, Andre said, with a shaky voice: "I'd rather just stop this if that's all right"
No deal
Andre and Price divorced last September, four-and-a-half years after meeting on reality TV show I'm a Celebrity... Get Me Out of Here!
Earlier on in the day, Andre had said he had "no negative feelings" about his ex-wife's remarriage.
Price and Reid, who have been dating for seven months, tied the knot in a "private, simple" ceremony on Tuesday.
The couple said in a statement: "We can't wait to get back and celebrate our marriage with our friends and family, who we know fully support our wishes."
According to Price's publicist, the star has insisted their decision to marry has not been made with any "pre-conceived commercial plan or media deal in place".
