Melbourne: Pregnant Mariah Carey has engaged a dog psychologist to prepare her pets for the arrival of her twin babies.
The Pop diva, who dotes over her three Jack Russells, does not want the exceedingly pampered pooches to feel rejected when her twin babies arrive.
She wants the psychiatrist to prevent any unwanted acts of jealousy.
Her boy and girl with husband Nick Cannon are due late next month or early May and their two homes in New York and Los Angeles have been lavishly decorated for their arrival.
"They can be jealous and possessive about their owners," the Daily Telegraph quoted an expert on the breed as telling the Daily Star.
