Daily deals website Groupon, which last year turned down a $6 billion bid from Google, has held talks with banks about an initial public offering that would value the company as high as $25 billion, according to Bloomberg.

The Chicago-based company ballooned to 50 million users in 2010 and is available in 500 cities in 40 countries. Not bad considering the two-year-old start-up was valued at $1.3 billion just last April.

Shira Ovide of the WSJ.com wonders if Groupon’s massive valuation, coupled with the reported $75 billion worth for Facebook, has the makings of another 1990′s tech bubble.

The majority of Vimpelcom shareholders voted for a deal that will involve taking on $20 billion of debt and diversifying into new markets, allowing it to claim victory in its long-running battle for control of Wind Telecom.

Norway’s Telenor, which has a 36 percent voting stake, had fought a battle with fellow major Vimpelcom shareholder Alfa Group to have it blocked. But the more than $6 billion cash-and-shares bid for control of Orascom Telecom and Italian group Windis is expected to complete in the first half, subject to regulatory approvals and financing.

Finally, 2011 looks like it will be a good year for Foster’s wine. The top Australian brewer has set April 29th as the date for the vote to spin-off its wine business, which has net assets of $2.8 billion.

Foster’s, already having rebuked an offer of $2.5 billion for the wine business from Cerberus Capital last September, is due to list the wine group on May 10th.

The move to spin-off the wine business would not only highlight the strength of its beer division but it would also make it easier for management to sell it.
