Lewthwaite is Interpol's top fugitive as fears grow that the terror attack on a shopping mall in Kenyan capital last Saturday claimed as many as 150 lives.
According to the Mirror, she has not spoken to her family in the UK for more than three years.
Her anguished cousin Anthony Bell said that Lewthwaite will always be in his heart forever and their family missed her dearly.
Intelligence experts fear Muslim-convert Lewthwaite and fanatics from the al-Shabab terror group responsible for the gun and grenade horror fled down a sewer tunnel beneath the streets of Nairobi.
Lewthwaite's cousin Anthony, who lives in Aylesbury, Bucks, the town where she grew up as an ordinary British schoolgirl, said the family relied on news reports for information about her.
Her father Andrew looked stressed after his daughter was named the world's most wanted fugitive, but refused to discuss about her.
Lewthwaite is understood to have slipped out of the East African country within hours of fleeing after the attack on the mall.
