AceShowbiz - Actress Rachel Bloom left Neil Patrick Harris red-faced after he failed to recognise her at the Tony Awards on Sunday night, June 10.

The actor was watching the ceremony at home with his young sons, when one pointed out that the woman featured backstage was repeating herself.

Harris took to Twitter and wrote: "Who is the woman in the top hat backstage at @TheTonyAwards? Gideon remarked that she says 'like' and 'oh my god' a lot. I'm confused..."

Rachel was a tad upset that Neil didn't recognise her, revealing they had met "numerous times", adding her husband was a writer on his sitcom How I Met Your Mother.

"I'm a big fan of yours," she said. "We've met numerous times and my husband, Dan Gregor, wrote for How I Met Your Mother for 5 years. Notably, he wrote the episode where your character finally meets his father."
