Los Angeles, Dec 5 : Hollywood star Tom Holland says girlfriend Zendaya is "the most honest" with him and he loves the tough love she gives him. Speaking in an interview for the SAG-AFTRA Foundation, he said: "Zendaya is probably the most honest with me. Which I love, 'cause you need that." Tom also revealed fellow Marvel stars Robert Downey Jr., 58, and Benedict Cumberbatch, 47, are the best advice givers, though he quipped: "Downey is very honest - sometimes a little too honest," reports femalefirst.co.uk. Tom continued: "I really respect Downey's opinion. He taught me so much and I always sing his praises, and I love the guy. I admire him. "Benedict Cumberbatch is someone that I ask for advice a lot about acting." Meanwhile, Zendaya has recently been forced to deny she and Tom are engaged. The 'Greatest Showman' star has been dating her co-star for three years now, and fans speculated that the couple might have taken their relationship to the next level when she appeared to be wearing an engagement ring on that finger. In a since-deleted post on her Instagram story, she clarified: "I can't post anything, you guys. I posted it for my hat. Like not for the ring on my right hand, you guys, seriously. You think that's how I would drop the news? You think, like, what!" She had captioned the original picture with a prominent ring on show with: "Let me just put the full body back so y'all can relax lmao." Tom recently admitted he is "lucky" to have found a partner who works in the same industry because they can talk about their respective experiences with mutual understanding. /IANS
