Arturo Gatti's mother says she found the behavior of her daughter-in-law odd the first time they met in 2007.
However Ida Gatti admitted she did have fun with the young woman, who was once arrested in connection with her son’s death.
Gatti testified Tuesday at the civil trial challenging her son’s will, which left all of his estimated $6.5 million estate to his wife, Amanda Rodrigues.
The will was signed in Quebec three weeks before the boxer’s death at a Brazilian resort in 2009.
Rodrigues was initially arrested in connection with Gatti’s death, but later released after Brazilian authorities deemed it a suicide.
Gatti’s family has never accepted the 37-year-old killed himself.
Last week, a panel of experts hired by the boxer’s former manager held a press conference to present evidence they believe shows Gatti’s death was a homicide.
His wife has dismissed those findings, citing the source of the financing for the private investigation.
Wrongful death lawsuit filed
Before Gatti’s mother took the stand at the Montreal trial Tuesday, the judge was informed of another twist in the plot in the fight over Gatti’s estate.
Last week, a judge in New Jersey ordered the boxer’s assets frozen.
The order followed the filing of a wrongful death suit by lawyers representing his five-year-old daughter, whom Gatti fathered with a former fiancée.
The suit alleges Rodrigues bludgeoned and asphyxiated her husband.
Gatti omitted his daughter from the will currently before the courts citing a separate agreement where he provided for her.
Rodrigues called her 'Ma'
On Tuesday, Ida Gatti testified that she thought Rodrigues was a beautiful girl, but she felt there was something not right about her.
She did not elaborate.
Ida Gatti testified she did grow fond Rodrigues, who later bore her grandchild, and found her charming.
She said Rodrigues once told her she loved Gatti and said Arturo was her life. But as the relationship went on, she said, the arguments between the pair became more frequent.
Under cross-examination, Gatti said she did have good times with her daughter-in-law and laughed as she looked at photographs of the two dancing and making lasagna.
She said Rodrigues eventually called her "Ma."
Gatti said, unlike her own daughters, Rodrigues wanted her mother-in- law to be present at the birth of her child, Arturo Jr.
However, the late boxer’s mother maintained Rodrigues shouldn't inherit his entire multi-million dollar estate because she pressured her husband into making her his sole beneficiary.
The civil trial continues in Montreal court this week.
