Lounge sighting in the afternoon of June 5th in the Elite section of the LO lounge in WAW: Germany's 2010 Eurovision winner Lena (Meyer-Landrut) with what appeared to be her Manager or PA.
Both were wearing black Adidas sport pants. He was constantly speaking on the phone, apparently organising her agenda, while she was relaxing and looking at her phone.
I thought that they would perhaps be on the same flight to FRA with me, as they left the lounge only slightly before me, but I did not catch sight of them in the terminal or later on board.
