The singer, 34, said she sent Eilish flowers with a note after the 18-year-old star bagged five Grammy awards in January.
Gaga told Apple Music: “Billie swept a whole bunch of awards so I said, ‘Let’s send some flowers’. I wrote her a note. For me, it’s healing because it hurt me that I didn’t get that. I’m going to be that for someone else.
“I’ve had a harder time with older women in terms of having a female mentor. Other than Celine Dion and Carole King, it’s proven difficult to have someone who would show me the way. So I really hope that young female artists – or young artists of any gender identity or sexual identity – will know that I am rooting for them,” Gaga said.
It’s not known if Eilish has taken Gaga up on her offer of mentorship.
“He’s been my mentor for a long time,” Gaga said. “I mean, he’s always challenged me to keep my head above water and it’s something that I always appreciate is that he knows when I’m down. He just does. And he knows because I hide, because I never want anyone to see me when I’m like that.”
Gaga released her sixth album ‘Chromatica’ last month. In a four-star review, NME’s Hannah Mylrea wrote: “Album six sees the provocateur welcome you to a fictional utopia where anything goes and everyone is accepted. We didn’t want to leave.”
