Cosby lawyer Tom Mesereau asked her on Monday.
Andrea Constand was calm and composed throughout her more than eight hours of testimony, opposite of her mother.
But Mesereau, who's best known for winning Michael Jackson an acquittal in his 2005 child molestation case, was incredulous as Constand denied being aware that Cosby was sexually attracted to her - even after he touched her thigh on one occasion and tried unbuttoning her trousers on another.
She told jurors last week that Cosby knocked her out with pills and then sexually assaulted her. Cosby, 80, says Constand consented to a sexual encounter.
She told jurors that she was concerned because her daughter hadn't been the same since leaving Temple in March 2004 and moving back to Canada, screaming in her sleep and waking up in a sweat.
She said she was "very combative" with Cosby, demanding he tell her the medication he'd given her daughter and what he'd done to her. She claimed she needed to understand precisely what Cosby had contributed Andrea, prompting him to confess it absolutely was a perscription drug that he neglected to call and perhaps not the allergy medicine Benadryl advertising he maintained.
The defence pointed to the phone records as evidence that she had kept in touch with Cosby in the following weeks at a level at odds with her account of having been assaulted. Mr Cosby's defence asked her.
Casting further doubt about the allegations, " Mesereau said Constand told authorities she called Cosby out of her phone that was university-issued just before she came to the night time of this attack to guarantee the gate would be available in his house. His first trial ended with a hung jury.
Cosby's defense attorneys argued last week that Constand was a con artist who was after Cosby's money. She has testified that she saw the former TV star as a mentor and had no romantic interest in him. But Mesereau said phone records showed she did not make any phone calls to Cosby's Philadelphia phone number that month.
Constand, the former director of operations for women's basketball, alleged she was drugged and sexually assaulted by Cosby, a former member of the Board of Trustees, at his Montgomery County home in 2004.

The hosts are expected to be without the services of Pedro Obiang, Winston Reid, Sam Byram, Andy Carroll and Michail Antonio. He continued: "I am proud of the team". "Last week after he made fantastic saves at Chelsea, I said to him: "Well done".
"I don't think so, duh I wouldn't even worry about it if I were you", Cosby replied.
Ms Jackson, who worked at Temple University at around the same time as Ms Constand, will testify that ahead of Ms Constand's allegations against Cosby in 2005, the accuser had mused to her about setting up a "high-profile person" and filing a suit.
When asked about the $3 million settlement between her daughter and Cosby, Gianna Constand said she did not know how much money was involved until she read about it in a newspaper.
Cosby's defense used its cross-examination to try to hint that her daughter was having money problems at Temple and using Cosby for his connections, rather than contest the story Gianna Constand told the prosecution of how Cosby confessed to her in a phone call he was a "dirty man" who improperly touched her daughter.
The judge has ruled that Jackson can take the rack but indicated after Constand was completed invisibly he could revisit the issue.
Mesereau hasn't set off many of fireworks yet, but in more than two hours of cross examination on Friday the veteran trial lawyer had Constand flustered with questions about whether she'd ever said she was affectionate toward Cosby, and a line of attack centred on her involvement in a Ponzi scheme.
Andrea Constand, Bill Cosby's main accuser at his sex-assault retrial, headed back to witness stand on Day 6 for more cross-examination.
The District Attorney's office continued with its strategy to draw parallels between the allegations of Cosby's other accusers, who testified last week, and Constand's.
He has been charged with three counts of aggravated indecent assault; a conviction on any of the charges could get him 10 years in prison.
The Associated Press doesn't typically identify people who say they're victims of sexual assault unless they grant permission, which Constand has done.
