MANILA - A word of warning for those who follow Angel Locsin on social media. The actress on Wednesday said she will not tolerate anyone who will lambaste her boyfriend, host Luis Manzano.

On Instagram, the "Everything About Her" star hit back at a follower who accused Manzano of being gay. In a screenshot taken by Pep, she was quoted saying: "Pakituro po sa akin kung sino nagsabi nang masapok ko ho nang todo."

The follower then quickly apologized and wrote: "Sorry, Angel. Nababasa ko rin iyon. Basta ang opinion ko ayaw ko siya sa iyo kasi napakabait mo. Idol na idol kita. Pag nasasaktan ka, nayayamot din ako."

To which Locsin replied: "Apology accepted po. Sana lang po next time you won't say things as a matter of fact kung wala namang basis. I won’t tolerate anyone lambasting him on my page…whether we’re together or not. Thank you for understanding po."

Last July, Manzano lashed out at one of his bashers on Twitter after the person claimed he is gay. Manzano explained that he retaliated because "some people just deserve it."
