ZOE Ball was replaced by Radio 2 star Scott Mills today as worried fans begged for an update on her return.
Presenter Scott failed to address her absence today but last week said "we're sending you love".
The veteran broadcaster, the BBC highest earning female presenter, has been off for six weeks - with insiders claiming "nobody knows what's going on" at the station.
Zoe, 53, usually takes the reins on the flagship show every weekday morning from 6:30am.
Today, Scott stood in for his second week running and kicked off the show telling fans: "Hello, good morning, how are you? Ready for a new week!"
He failed to mention Zoe, but added: "This weekend, I saw my friends, my family, and I'm trying to get into green tea ..."

He said his mates convinced him to drink it and insisted after a couple of days it is "just like coffee".
But he ditched the plan on Monday morning, and forced himself to drink pure vegetable water which is said to deliver youthful effects on the skin.
BBC Radio 2 posted a video of the moment on Instagram, with Scott heaving at the smell.
But beneath the video, one listener penned: "When's zoe back?".

Last week Scott, who is usually in the drivetime hotseat, addressed his appearance on the breakfast programme.
He said: "If you set your alarm every morning to go off at 6:30am and normally Zoe comes on, please do not freak out. You have not overslept.
"If you've just put us on this morning, it's Scott Mills in for Zoe for the next few weeks. I'm sending you all my love Zo', as are the team."
Zoe's absence from her BBC Radio 2 show has again been put under the spotlight.
A source has told how mystery surrounds Zoe's absence and said: "Nobody knows what has happened but everyone loves Zoe.
"We hope everything is okay.
"Zoe is so loved at the BBC so to not have her around is really noticeable."
The star took the summer holidays off and had not been on air since July.

The BBC also released a statement on the broadcaster's future earlier this month.
They said: "Zoe will return to the Radio 2 Breakfast Show later this month."
