Bolasie spent much of this season's first half playing alongside Grealish while on loan to Villa from Everton.
But the DR Congo winger has since joined the Belgian side Anderlecht after cutting short his Aston Villa spell in January.
And after the Soccer AM Twitter account asked its followers to fill in the following blank, Bolasie replied:
Grealish is expected to return for Villa later this month, having been out since the start of December with a shin injury.
And Dean Smith's side have only won two of their 13 league and cup games without him, halting their promotion hopes.
Bolasie scored the first goal of his Anderlecht loan spell on Sunday - a stoppage-time winner to help Fred Rutten's side overcome Royal Antwerp.
The 29-year-old, for whom Everton are said to have paid £25 million to sign in August 2016, is under contract until 2021 on Merseyside.
Is the Everton player right about Aston Villa's Grealish?
