Sean Lennon regrets not making up with estranged best friend MAX LE ROY before his death, even though the socialite slept with his girlfriend behind his back. The son of late BEATLE John Lennon based his new album FRIENDLY FIRE on his split from Bijou Phillips, prompted by his discovery of her 1994 infidelity with Le Roy. But Lennon wishes he could go back in time and make peace with his pal, because Le Roy died last year (05) in a road accident while they were still feuding. He says, "The most terrible part of the story is that Max passed away and I feel very stupid for not having reconciled with him."
