The presenter of US TV show Millionaire Matchmaker has apologised for saying that gay men cannot be faithful.

Dating expert Patti Stanger, 50, appeared on Bravo’s Watch What Happens Live on Sunday.

Stanger, who runs a dating agency for millionaires, was speaking to a caller who asked for advice on long-term relationships.

She said: “In the gay world, there’s always going to be open [relationships]. There’s no curbing the gay man. You’re going to be OK.”

Show host Andy Cohen, who is gay, appeared surprised and said: “So wait, gays can have open relationships?”

Stanger replied: “I have tried to curb you people.”

But Cohen pressed the issue, saying: “I am a gay and am down for monogamy.”

Stanger retorted: “When’s the last time you had a boyfriend?”

On the same programme, she claimed that “Jewish men lie”.

Yesterday, she defended her remarks on Twitter, claiming that gay men “love variety” and prefer to “hook up 1st, get to know the man after”.

But by yesterday evening, the matchmaker apologised for causing offence.

Her statement said: “I am so sorry. I did not mean to offend anyone with my comments last night on Watch What Happens Live.”

Bravo also said it regretted her remarks, adding: “Her comments are not representative of the network’s beliefs and opinions. We apologise for the offence it caused.”

Stanger has a reputation for outspoken, even offensive, advice.

She recently advised clever women to pretend to be stupid, claiming: “[Men] don’t like [smart women] before they are married. You’ve got to dumb it down a little because men are not that bright.”

She has also urged redheads to dye their hair and curly-haired women to straighten theirs,
